How To: Stretch, shift & reflect the graph of a square root

Professor ElvisZap teaches you how to stretch shift and reflect the graph of a square root. A square root function is the opposite of a squared function. You start with y=square root of (x-1) it becomes 0<=x-1. then 1 <=x. You use the graph and solve it as you would for any function using small values first, then you have y=square root of x - 1, the domain 0<=x. This shifted the graph down 1 unit. 0=square root of x - 1, 1=square root of x, 1=x. Then the range is [-1 + infinity). Continue in ...

How To: Find the circumference of a circle quickly

In this instance we are going to Find the circumference of a circle by applying formula C=2pr where 'C' is circumference of a circle, approximate value of 'p' is 3.14 because it is irrational number and 'r' stands for radius i.e. half of diameter. So by applying this formula we can easily calculate circumference of a circle if radius is given or we can also calculate radius if circumference of a circle is given. One thing to remember is that unit we use for circumference of a circle is cm, in...

How To: Make a cool paper box

The box requires 2 6"x6" sheets of paper in 12 colors, that is 24 sheets in total, as well as one 6.25"x6.25" and one 6.5"x6.5" piece of paper, both preferably of the same color. Construction will also require some paper glue at certain points. The construction of the box is sectional; there is an outer box, with the inside "concertina" mechanism formed from 12 identical units glued together. The sectional nature of the construction would lend itself well to people working in groups in a clas...

How To: Use crawl control on the 2010 Toyota 4Runner

Have you ever driven your car on rough terrains? Seems difficult to handle it. You can now steer, brake and accelerate at the same time with the new 2010 Toyota 4Runner. It has introduced a new technology called crawl control which helps determine optimum combination of speed and traction. It processes inputs from wheel speed sensors, vehicle's stability control computer, G-sensor and the engine control unit. To start this system, shift the transmission to neutral and then the transfer case t...

How To: Find the volume of a solid object

This video shows the process of finding the volume of solid. The video is simple and easy to comprehend. The video takes the example of a rectangular solid and a solid cylinder to explain the method to find the volume. The video shows the step by step method to find the volume. The first step involves finding the area of base. After this, the area is multiplied by the height to find the volume. The unit of measurement is also taken into account in the video.

How To: Solve direct proportions

You can solve any proportion using the fundamental rule of proportions. First you must build the proportion if you are given a word problem. Decide using logic whether it is a direct proportion (more on one side means more on the other). If so, find the parts of the equation that use the same units and make a fraction with these, putting the smaller number on top. The number left over is linked with one of the other two numbers in the fraction--use logic to figure out which. Put it in the sam...

How To: Find the area of complex figures

In this tutorial the author explains how to compute the area of a complex figure. Now he first defines what a complex figure is by saying that a complex figure is a figure made up of two or more basic shapes. He uses an example to convey his idea and breaks that sample figure into basic squares and rectangles. Now he computes the areas of these individual units separately and finally puts them together to arrive at the final area of the complex figure. If you are looking to compute the area o...

How To: Find the area of a triangle in geometry

This is a tutorial on how to find the area of a triangle. To show the viewer how it is done, the video walks us through a simple example step by step. The first step is to find the base and the height (in this example 5 and 6). The next step is to multiply them together (making 30). Next, the answer is divided by two (to get 15). Finally, the units are written next to the answer (in this case inches squared). This is beneficial as it is a very easy and user friendly way of learning how to fin...
