How To: Find the equation of a perpendicular line easily

In this video the instructor shows how to find out an equation of a perpendicular line. If you need to find the equation of a line passing through the given point and is perpendicular to another line, the first thing you need to do is compute the slope of the given line. Obtain the slope of the equation by writing it in the form of y = mx + b. Now the product of slopes of two perpendicular lines is a negative one. So the slope of our required line will be the negative inverse of the slope of ...

How To: Understand integers and the number line

User DayTeacher helps you understand integers and the number line. When numbers were conceived, man had the basic concept of small numbers. The first things you learn in a language are numbers. The weather might have had an impact on numbers, as temperatures dropped below 0. When talking about years Before Christ (BC), you could say 1000 B.C. is actually -1000. Being in debt means negative money. Two days ago is -2 days from the time we are talking about. Integers are positive whole numbers, ...

How To: Graph half an ellipse

If you are given an equation of ellipse in the form of a function whose value is a square root, you may need to simplify it to make it look like the equation of an ellipse. Now equate the function to a variable y and perform squaring on both sides to remove the radical. Now simplify the equation and get it in the form of (x*x)/(a*a) + (y*y)/(b*b) = 1 which is the general form of an ellipse. Now you will have the x and y intercepts which are a and b respectively. Using this values graph the eq...

How To: Solve equations & inequalities with absolute value

In this tutorial the instructor talks about various strategies for solving equations and inequalities involving absolute value. To do this the first step is to isolate an absolute value. An absolute value is exactly equal to a number. If that number is less than zero then there is no solution. So, if you have an absolute value that is less than a number it means that the real value lies in between negative and positive value of that number. If your number is less than zero then it is empty se...

How To: Start a fire with your cellphone

Ever wanted to know how to make a fire with your cell phone? All you need is a cell phone, a brillo pad, and material for tinder. First take the battery out of your phone and find the positive and negative contacts on the bottom of it. Next tear off a chunk of the brillo pad, roll it up until you have a twisted piece about an inch long. Bend the steel wool over and touch an end to the positive and the other end to the negative contacts on the battery. That causes the steel wool to smolder--no...

How To: Test a vehicle alternator with a standard multimeter

Richpin demonstrates how to test an alternator with a standard multimeter. First make sure that the vehicle's battery is fully charged. Take the negative lead of the multimeter and put it on the negative post of the battery. Place the positive lead of the meter on the positive lead of the battery. Set the meter to DC voltage using the 20 scale and read the display to ensure the battery is fully charged. Next start up the vehicle and see what the alternator is producing. The display should now...

How To: Match quadratic functions

This is the demo showing how match quadratic equations in the graphs. Plug in x=0. So everything with x cannot disappear. There is only one negative three in the equations. Let's look at the equations that has the four as y in the set. One of the difference between each equations are the negative in front of the x square and not in the second one. B is the set which opens down and C is the set which opens. Now lets look zero as y on each set. Both of them are opened. Let's look at X intercepts.

How To: Evaluate square roots

This is the video about how to evaluate square roots. The square root of a number is a number that you can square to get it, that is, a number that you can multiply by itself to get the number. So, 2 is a square root of 4, because 2 x 2 = 4, and 3 is a square root of 9, because 3 x 2 = 9. (-2) x 2 is also 4 and (-3) x 2 is also 9. Numbers that have square roots always have two, a positive one and a negative one, but the square root symbol means only the positive one, so we can have one answer...

How To: Test for symmetry algebraically

This video teaches you how to test for symmetry algebraically. You will need to know the basic formats of graphs and the (x,y) setup. Once you get your equation of the line, you will need to replace y with negative y and x with negative x and solve the equation. You will need to solve for x and also for y for the odd and even. If the equations do not equal each other then they are not even or they are not odd. If this is the case then the lines are not symmetrical and that is how you test for...

How To: Use a sodium potassium pump

This is a great video presentation of how Sodium Potassium Pump can maintain a voltage gradient across a cell. It also discusses various things like the differences between positive and negative charges and positive and less positive charges etc. The video tries to explain a lot of things happen within a cell when you fluctuate the voltage of sodium as well as positive and negative ions within a cell. You must watch it yourself to see the changes happen within a cell when you make some changes.

How To: Find the slope, given a graph

If you watch this video, you will learn what slope is, and how to find it. Slope is defined as rise divided by run, where rise in the increase the Y coordinate and run is the increase in the X coordinate. For example, if you pick two points, you can travel from the left point to the right point. However many points you go is the run. How far up you go is the rise. For example, if your rise is 4 and your run is 2, then you divide 4 by 2 to get your slope, 2. When you're finding the rise, if yo...

How To: Use jumper cables to jump start a car

This video explains how to use jumper cables to jump start a car. First, determine that a dead battery is the reason your car is not starting. If the engine cranks when you turn the key, the problem is not the battery and jump-starting won't help. If the windshield wipers, lights and heater blower all work, the battery is probably fine and you may have a bad starter. A jump-start won't help if you have a bad starter. If you hear no sound at all when you turn the key or if the engine cranks ve...

How To: Jumpstart a dead battery

If your car has a dead battery, jumper cables can be used to connect to a car with a good battery to start your engine. Begin by positioning the two cars side-by-side, turn off the engines, and lift the hoods to access the batteries. First, attach the red cables to the positive terminals of each battery beginning with the dead battery. These terminals are usually marked with a plus sign or in red. Next, attach the black cable to the negative terminal of the good battery. The negative terminal...

How To: Simplify exponential expressions in basic algebra

The video shows how to solved mixed property problems using the exponent rules. See if there are any rules you can apply to the problem until you get to a point where you can't simplify anymore. The instructor shows in the example problem that the two bases are the same, but there is extras happening the numerator. The power to power multiply rule is applied removing the extra issues from the numerator. Next the quotient rules is applied as there is the exact same base to the power so we keep...

How To: Understand nth roots and operations on radicals

This video teaches us the concept of nth roots. The video starts with the square root of constants. We find the number which when multiplies by itself for two times results in the constant inside the square root. Then we find the square root of variables. Here again the same concept is used. We find the variable which when multiplied by itself for two times results in the given variable. Then we find the cube root. Here we find the number which when multiplied by itself for three times result...
