This video tutorial belongs to the Education category which is going to show you how to reduce fractions to their lowest terms. For doing any operation with fractions like addition, subtraction, multiplication or division, they need to be reduced to their lowest terms. To do this look at the numerator and the denominator and decide what number can divide both of them. Continue dividing till you can no more divide them. Now you get the lowest term of the fraction. For example, 2/4 can be divid...
Mark Wallace shows us how to use a wide lens for portrait photography. A longer lens minimizes distortion in your picture and it maximizes what type of view you can see, so you can see more of the thing you are taking a picture of and less of the background. These lenses help keep the picture clean and uncluttered. You can see the difference between a wide and short angle lens by taking pictures with them and looking at the differences between them. There is also a zoom available, which makes...

Avenged Sevenfold has been one of the biggest rock bands in the world for a long time, but their most recent single "Nightmare" might be their biggest hit yet. It's a beautiful, haunting song, and like much of A7X's work it translates well to some furious piano playing. This video will show you how to play the song on piano or keyboard in the simplest terms possible, but it's a hard song if you are new to piano you might want to look elsewhere.
Slideshow is such a dirty word. Most people immediately think of boring family reunions or 1980's corporate meetings when they hear it. That's probably why web designers prefer using the term image gallery to refer to their slideshow-like works. This video will teach you how to make an automatic image gallery using Flash CS4, which is a slideshow where the images advance automatically on a timer.
While breadboarding may seem like some odd combination of snowboarding and consuming the fluffy pastry at the same time, it's actually just the technical term for using a construction base to build a prototype electric circuit. Breadboards are solderless so they're great for circuit design and are reusable.

It's nothing but your topic and what you want to say, so don't get scared by the term "thesis statement". Practice writing your paper using this saying instead of thinking of the thesis statement term. Usually in school you are given the topic you are going to write about it, so just state that topic and defend your position on it. It will be the same in real ...
This video is aimed at beginner level viewers and shows one of the basic techniques involved while solving linear equations having one variable.
In this video the instructor teaches about equivalent fractions. When given a problem to determine if two fractions are equivalent fractions the first thing to do is write them in the lowest terms. A fraction is said to be in the lowest terms if the greatest common divisor of both numerator and denominator is one. So cancel the common factors in the numerator and the denominator till you arrive at the lowest form and finally compare them to determine if they are equivalent. An equivalent frac...
Finnish is an unusual language, which can make it tricky for foreigners to learn. Instead of relying on a book, the Learn Finnish video language-learning tutorial series shows a photograph of a vocabulary term while pronouncing the word in Finnish. This technique allows the student to associate the object itself, rather than the term in their native tongue, will the Finnish word, thus allowing for maximum comprehension and absorption. In this video segment, the alphabet, "aakoset" in Finnish,...
So, you snapped a great picture, but it's just a little off-center. Usually, rotating a photo requires cropping it, which will lower the overall quality of the image. That's not the case on the iPhone 11, 11 Pro, and 11 Pro Max, however. Apple's new flagships allow you to rotate images without cropping them. The only issue? The feature isn't enabled by default.
Zabernism. What exactly is it? It's a term that originated in 1912, during an incident involving an overzealous soldier who killed a cobbler for smiling at him is Saverne, a small town in Alsace in north-eastern France. The said event ultimately triggered an intervention from the army who took over the power from local authorities.

Iambic pentameter sounds, well, scary. The phrase is super long and most people don't know off the bat what it means. But it's really not as difficult as you think to understand this poetry term.
This video shows the method to simplify rational expressions. The example used in the video is multiple of 4 and x square plus multiple of 4 and x plus 1 or (4x^2 + 4x + 1)/(2x^3 + 11x^2 + 5x). As the first and last term is a perfect square we get the simplified numerator as (2x + 1)(2x + 1). Next, the denominator is simplified. Taking the common factor out we get x(2x^2 + 11x + 5). Now we factorize 2x^2 + 11x + 5. We get (2x + 1)(x + 5 ). Now, writing the terms in numerator and denominator w...
In this video tutorial the instructor shows how to solve exponential and logarithmic equations. Solving exponential equations can become very difficult if it involves large numbers. To solve these kinds of complex equations you need to get all the numbers to the same base number. The base number raised to some number should give you your original number. Now if you write the numbers as exponents of your base number you can directly equate the exponent part and solve for the missing variable. ...
In this video the instructor shows how to factor a polynomial. A polynomial having three terms is called as trinomial. Now if you factor it you will obtain two binomials whose product will be the original polynomial. Before factoring a polynomial you need to find out if the polynomial has a GCF. Look out for the common variables in all the three terms and pull them out which is the GCF of the polynomial. This simplifies the original equation to a polynomial which is of lower degree. Now facto...
An educational video by http://JustMathTutoring.com that shows how to use implicit differentiation to find a 2nd derivative of an equation.
In this video, the instructor shows you how to graph quadratic equations. When you have a quadratic equation in terms of x and y, first try to identify the coefficients of the terms. Now use front end of the quadratic formula to find the line of symmetry which is the first half of the vertex using the formula x = -b/2a. This gives the line of symmetry. Next, plot the line using a few points starting at the line of symmetry. Take sample values of x and find the corresponding values of y on eit...
In this video the instructor shows how to use proportions to solve fractions. When you have a proportions problem with an unknown term, cross multiply and divide it to get the value of that unknown term. For example if given 7/8 = m/4, cross multiply 7/8 with 4, giving 7/2 which is the value of the unknown variable m. So if two quantities are proportionate then you can equate them as shown in the video and cross multiply to get the value of any unknown variable. Proportions are just fractions...
In this video, they demonstrate how to factor a trinomial. A trinomial is a polynomial with a quadratic term in the form, ax^2+bx+c. To factor this polynomial first multiply the a and c term. You must fine two numbers that multiply to a*c and add up to b. Once you have figured out the two numbers you place the two numbers (D and E for example) in the equation (1/a)(ax+D)(ax+E). It takes a bit of practice to be good at deciding what D and E are, but the best way is to make sure that D*E = a*c ...
In this tutorial the instructor shows how to solve percent equations. The general form of a percent equations is that a is b% of c. As there can be three kinds of variables a, b, c, the questions involving percent equations can be of three types having one of the three variables unknown. These kind of percent statements can be solved easily by setting up an equation. So, to convert percent statement into a equation replace the unknown term with n, the 'is' term with equals sign and the '%' si...
In this video the instructor shows how to solve rational equations. If you have fractions in your equation, then you need to factorize the denominators first. Now compute the least common denominator of all the denominators of the fraction. Next multiply both sides of the equation with the least common denominator. This cancels out all the denominators of all the fractions and you are left with a linear equation. Now simply multiply the remaining terms in the numerator and add common terms to...
In this video, Yuri Elkaim will teach you how to get six pack abs using cardio and strength training. He breaks down the discussion of cardio vs. strength training for burning fat and building muscle. In the video, Elkaim stresses high-intensity interval training (HIIT), in which he says you will burn more calories, and therefore lose more fat if that is your aim. Furthermore, working at a higher intensity for longer periods of time increases your cardiovascular strength to an even higher deg...
In this video, the instructor shows how to find the equation of a circle given its center point and a tangent line to it. To do this, take a graph and plot the given point and the tangent on that graph. Now, from the center of the circle, measure the perpendicular distance to the tangent line. This gives us the radius of the circle. Using the center point and the radius, you can find the equation of the circle using the general circle formula (x-h)*(x-h) + (y-k)*(y-k) = r*r, where (h,k) is th...
