This video shows how to calculate the circumference of a given circle. The video first describes the circumference or perimeter of a circle as the distance around the outside of a circle. To find the circumference we need either the radius or the diameter of the circle. When you know the diameter of the circle, the formula to find the circumference denoted by 'C' is 'pi' times the diameter, where 'd' is the diameter and 'pi' is a constant, the approximate value being 3.14. And when you are gi...
On Yay Math, Robert Ahdoot, founder of Yay Math, will show you some square root functions and some inequalities. He begins with the problem y=x². Then he makes a sketch with two intersecting lines in a t shape. The problem is illustrated by a curved U shape, the U's bottom resting on the horizontal bar, which represents x, while the center takes the vertical line. The vertical bar represents y. This U is directed up because the x² is a positive number. If the number were negative, the U would...
This video is about using the elimination method to solve a linear system. The lady presenting this video says that elimination method means that one of the two variables has to be eliminated while adding up the two linear equations. She then explains the example equations 6x-2y=66 and 5y=-29-2x. She asks you to first line up x and y. So the second equation is rewritten as 2x+5y=-29. Then she says that, to eliminate a variable, we should have their variables equal in value but of opposite sig...

Can you speak like the Beatles? Not bloody likely! Well, you CAN learn to speak with a Liverpudlian accent IF you check out this video and wrap your head and tongue around the words. This accent is a wonderful one and recognized around the world as the dialect spoken by the Fab 4. It almost sounds Scottish, but it's 100% working class England. John Lennon had the best example out of the Beatles of this accent, with George Harrison coming second. Paul and Ringo did not have particularly good L...

In this tutorial, we learn how to draw different types of anime/manga hair. Different types of hair can completely change the look of a character. For example, if you are going to draw hair on a girl manga character, you will want to make it curly and long. Use long lines with bangs to make this hair look more realistic. For guy manga characters, you will want to add a lot of triangles to the hair to make it look like spikes all over and give him short bangs as well. Give each of these your u...
This is a video tutorial in the Education category where you are going to learn how to understand polyatomic chemical formulas. When writing the formula using polyatomics, the same cross-over rule applies. 1st identify the metal and non-metal. Then you write the symbols, write the charges, cross-over the charges from top to bottom, remove the charge and simplify the numbers and remove the 1s. for example, iron (II) phospahate. The "ate" ending implies that phosphate is polyatomic. The symbol ...
Making web games using Flash and all the other plugins out there is fine, but compatibility and resource use are always going to be issues for them. Amazingly enough though, HTML5 is far enough along now that someone has made BioLab Disaster, one of the first if not the first web game to be made entirely with HTML5 and Javascript with zero plugins. The game's maker, Dominic Szablewski, was nice enough to make this video describing what he did to program this landmark game. It even describes w...
This video tutorial speaks about how to create a dramatic effect to an image using only Camera Raw in the Bridge program of Photoshop. In this example, the picture was first brought into the program and the fill light was turned upwards in order to lighten up the dark foreground. The white balance of the picture was changed to cloudy to add a nice effect and the color temperature was changed to make the picture appear warmer. The various parts of the picture can then be changed individually b...

It's funny how unevenly the real world keeps pace with science fiction. Smartphones have capabilities that Gene Roddenberry never imagine a portable device could have, but guns still use tiny powder cartridges to launch hunks of metal at things. The phasers, ray guns, and blasters of Star Wars, Star Trek, and other sci-fi works have yet to appear. Don't let that hold you back! This video will show you how to make a cool retro ray gun prop that you can use with a Halloween costume or in a film...

After Effects allows you to do all sorts of amazing things to your videos and images, but it cannot do it all alone. This video will show you how to use an After Effects plugin called Normality 3 to make lighting adjustments to 3D assets on the fly, having already rendered out a normal pass using either Cinema 4D or Modo (you can use other 3D software too, but those two are both shown as examples in the video). It will also demonstrate how to render out the normal passes.

This video tells us the method to find the surface area of an aluminium can or cylinder. The surface area includes the outside area of the curved portion and the aluminium top and bottom. The formula to find area is the multiple of 2, pi, r, r+h or (2)(pi)(r)(r+h). The radius of the cylinder is the radius of the circular top or bottom. In the example shown in the video, the radius is 4 inches and the height is 12 inches. Substituting the values in the formula, we get the surface area as (2)(3...
The video describes how to convert any unit of weight to any other unit. The example used here is conversion of pounds to kilos. Going to the Google homepage, the desired conversion should be typed in the search box directly, e.g., "150 pounds in kilos". Click the "Google search" button and Google will use its built-in converter to give the result, in this case, 150 pounds is equal to 68.0388 kilos. This, if it is ones own weight, will of course make anyone feel better, because kilos look les...
First of all you have to check the root which has started circling. Then notice that there is a dark portion at the bottom of the trunk. You can prevent this problem by avoiding to plant too deeply and not to leave in the pot for too long. You have to plant it at the right depth. Now check the roots of the bigger tree that has died. You shall notice that the roots have started circling around a part and then they stop the circulation to the top of the tree and then the tree dies because it wa...
To solve a proportion for a variable you should employ cross multiplication. The basis of cross multiplication is the property which states that the product of the numerator of one fraction and the denominator of what it is set equal to is equal to the product of the remaining denominator and numerator. For example if you have x/15=21/45 you simply need to multiply x by 45 and 15 by 21 then set them equal to each other. The result of this is 45x=315. To solve this new problem for x, divide bo...

This video shows you how to do a mathematical representation on computing the nCr function using a TI-89 calculator. You can write the nCr notation in different forms. It can be simplified from nCr to C(n,r). The symbol can either be read "n choose r" or "n taken r at a time" which are from it's probability applications. On the example to find "26 choose 17", go to the Home screen of the TI-89 calculator and then go 2nd 5 which is Math. Go choose probability and then to nCr to type in (26,17)...
This video instructs on how to find the sum of fractions that have the same denominator. In order to do this, all that needs to be done is to add the different numerators together, then put the sum of those numbers over the common denominator. The example used is 2/9 + 1/9 + 5/9. The first step is to add the numerators which gives you 2 + 1 + 5/9. Then simplify the fraction adding 2 + 1 + 5 which equals 8. That is your numerator. The denominator does not change because it is common, so the fi...
