First of all cut of the top and the bottom of the cylinder to get two circles. Now take a scissors and cut of the cylinder into two halves from the top to the bottom as shown. Now you get a rectangle shape. You can easily measure the length of the cylinder but to measure the base is a problem. So mark a point on the table with tape and also make a mark on the can or the object you want to measure. Now place the two points over each other. Now use a ruler as a guide and move the can so that th...
In this video the author shows how to do similarity transformations. He says that similarity transformations are used to draw the similar images at a different location and the k value is most important while doing this kind of transformation. He says that a negative k value tells that the copy of the shape will end at the opposite side of the origin to the original shape. He says that a positive k value tells that the copy will lie on the same side of the origin. Next thing about the k value...

The idea of finding the area under a curve is an important fundamental concept in calculus. Consider a function y = f(x). Now the area under the curve is to be calculated. The area under a curve problem is stated as 'Let f(x) be non negative on [a, b]. Find the area of the region lying beneath the curve y = f(x) and above the x-axes, from x = a to x = b. Note that finding the area under a curve will imply that you are dealing with a non negative function. The way to approach is to divide the ...
This video is about Level 2 atomic concepts, specifically the Pennium Lab. This helps you understand how atomic masses are derived for the periodic table. This teacher demonstrates how to do the calculation. He first reviews the Isotopes as they are different masses of the same type of atoms. He uses chromium as his example. It has a different number of neutrons in the nucleus. Using the equation, it could have either 26, 28, 29 or 30, with its 24 protons. So he subtracts the atomic number fr...
The video shows how to make an extra long ping pong smoke bomb. For this we need a long sheet of aluminum foil (length of the foil depends on the number of ping pong balls we use), 12 ping pong balls is used in the video (any number of balls can be used), a pair of scissors and a lighter.
Two college students; Kevin Martin and Joey Smokey introduce the concept of Molar Mass. They start of by explaining what molar mass is, which is the relationship of a mole and a gram, it totals up the weight(in g)of a molecule. An example: say you have this compound, Sodium phosphate (Na3PO4). You know you have three sodium atoms, one phosphorus atom, and four oxygen atoms. You basically find the weight of each atom, if you have three sodium atoms, you multiply it's atomic mass by 3 (the numb...
This video teaches you how to solve a linear system by mathematically graphing it out. The video starts off with a problem, asking to solve the system, with two given equations. To solve the system, one would insert 0 for x and solve for y in the first equation to obtain a point. Then one would insert 0 for y and solve for x at the second point. Afterwards, insert 1 for x and solve for y to obtain the third point. For the second equation, do the same thing, inserting 0 for x, 0 for y and 1 fo...
This video shows the method to find the variance and standard deviation using Excel. The variance shows the variability of the data points from the median. We find the difference of the median and the mean. We write the formula using '=' sign. The median and data points are put in it by selecting the appropriate cell. The median is made an absolute constant by pressing the F4 key. This is squared by using '^2'. This is multiplied to the frequency using '*'. The result is found for all the dat...
In this video the instructor shows how to use the Round function and also format numbers in Microsoft Excel. Normally while calculating formulas in Excel, the formatting of numbers can get you into a lot of trouble and to get around this problem you need to use the Round function. To do this take some sample data in a Excel work book and apply any formula that you want on the data to arrive at some calculation. Now because of this formatting some times you can arrive at a wrong result as show...

This is the video about how to Find the equation of a line. The equation of a line with a defined slope m can also be written as follows: y = mx + b where m is the slope of the line and b is the y intercept of the graph of the line. The above form is called the slope intercept form of a line. Step1 Set m to a fixed value (m = 1) and change b (b = 1, 2, 3, 4, -1, -2, -3, -4). Compare each value of b to the y-intercept of the line obtained. Step2 Set b to a fixed value (b = 1) and change m (m =...

Math can be tricky, especially when you're trying to decipher algebra. It's a love-hate thing; if you don't love math, then you hate it, and there's no in-between. But it doesn't have to be a pain to solve a few problems. It's actually quite simple once you figure it out. An algebraic equation is an equation that includes one or more variables. These equations can be solved as long as the number of variables does not exceed the number of equations.
The video shows us how to find the area of parallelogram using geometry. Here in this video it is done by using an example where the parallelogram is given ABCD. The area of the parallelogram is base times height (bh). Here the base is given as 15 but the height is not known but it is represented by the segment BD. To find the value of h, let’s use right triangle BDC on the right side of the figure. Since base is 15 and the opposite side of the parallelogram is congruent, the hypotenuse of th...
