How To: Work with complex numbers

In this algebra video the instructor shows how to work with complex numbers. When you have a positive number under the square root, you can easily find its value by writing it in the form of product of numbers, and then solving. That is, to find the square root of a positive number, you can find another number which multiplied by itself gives the original number. This new number becomes the square root of the original number. But when you are asked to find out the square root of a negative nu...

How To: Use math rotations in pre-Algebra

On yourteachermathhelp teaches you how to use math rotations in pre-algebra. In this example, the shaded object represents the original one, while the empty object is the new, rotated one. Here, the original object has suffered a quarter of a turn, or a 90 degree turn. You can see that the top of the shaded figure or object has been turned to the left. This is in the opposite direction in which the hands of a clock move. This translates to a 90 degree turn in the counter-clockwise direction. ...

How To: Factor trinomials

In this video, the instructor shows how to factor trinomials. An equation is a trinomial if it has three terms. If you factor a trinomial, you are left with two binomials which are the factors of the original trinomial. Multiplying them would result in the original trinomial. Now factor the last numerical term such that the sum or difference of those factors gives you the numerical coefficient of the middle term. Now split the middle term according to the factors obtained in the previous term...

How To: Solve an equation with a radical under a radical

In this video the instructor shows how to solve an equation with a radical under a radical. If you have an equation with a square root on both sides, with one of the sides having another inner square root under the original square root, it can be a little tricky to solve it.

How To: Simplify complex fraction

In this video the instructor shows how to simplify a complex fraction. A complex fraction is a fraction that has fractions in both the numerator and the denominator of the original fraction. Complex fractions can look intimidating but are generally simple to solve, as shown in this video. A fraction is nothing but a division of its numerator and its denominator. So in a complex fraction basically you are dividing two fractions. Now you can turn this division into multiplication by multiplying...

How To: Factor a trinomial with negative leading coefficient

In this video the instructor shows how to factor a trinomial with negative leading coefficient. Most of the students are confused when they have to factor a trinomial with a negative leading coefficient. But there are many ways to solve these kind of problems as shown in this video. One way you can do is that take out the greatest common factor (GCF) of -1 from the equation. So pulling the -1 gives you the original trinomial with all the signs of the terms changed. Now go on and factor the ne...

How To: Find the percent increase or decrease in a quantity

This video shows us the method to find the percent increase or decrease in a quantity. This can be done in 30 seconds. The formula states that the percentage increase or decrease is equal to the product of the ratio of amount (increase or decrease) and the original amount and 100. This is explained by two examples. In the first example the amount of increase of the price of groceries is found by taking the difference of the new price and the old price. This is divided by the original price an...

How To: Figure out the price of something at a discount

In this tutorial the tutor shows how to work around with discounts. He shows how to find out the price of an item after discount is applied to it. He says that this is a regular situation faced by us when we visit shopping malls etc., Now he says that we need to multiply the original price with the discount percentage and divide it by hundred. This gives us the discount amount. Now he instructs us to subtract this discount amount from the original price to get the final discounted price. He f...

How To: Draw a reflection in Geometry

In this tutorial the author shows how to draw reflections in geometry. He shows how to draw them with a couple of examples in which he uses a reflection line and an object whose image is to be reflected. Now he draws perpendicular lines to the reflection line from the vertex of the original figure. He draws similar lines to all the vertexes all of same length and now after joining the ends of those lines a reflection of the original figure is obtained. This video shows a step by step method t...

How To: Write a slope-intercept equation perpendicular to line

In this tutorial the instructor shows how to write a Slope-intercept equation that is perpendicular to a line and passes through a point. He shows how to do this by solving an example with sample values. He says that the slope of a line perpendicular to the original line is the negative inverse of the slope of original line. Now he writes down the slope value in the general equation y = mx + c, and by substituting the sample value in the equation he obtains the value of the Y-intercept c, thu...

How To: Cast an RTV mold

This animation shows the various steps taken when creating an RTV mold. First, risers are put on the part to allow air to escape from the final mold. A thin film is attached to the part, which will act as a seam for the final mold. A box is built around the entire structure, and it is filled with silicone rubber. Once the rubber has cured, the box and risers are removed, the mold is opened at its seam, and the original part is removed. Any type of urethane can now be injected in the mold to c...

How To: Kern and typeset in Cinema 4D

Despite a lack of native kerning tools for typesetting in Cinema 4D, it is possible with a little bit of effort. Letters and characters can be spaced individually using Mograph and the plane effector. Another solution is to first kern the entire block of text externally using Illustrator and Photoshop, and then import into Cinema 4D.
