In this video the instructor shows how to convert between different metric units. He shows a three step approach to do this. He shows a hierarchy of units arranged from millimeters to kilometers etc. Now he says that the first step is to identify the current units of the values. Next you need to identify the units you want the value in. Next he asks you to see which direction you have to move in the graph and by how many places and now he says that to convert the value in the new units you need...

This is video for how to divide large numbers by doing long division with easy methods. This video describes that dividing the "Dividend" with "Divisor" to get the "Quotient" and "Remainder" if they exist. In the given example first "25" taken as the Dividend and "5" is will be the Divisor. Divide this value the multiplication is needed. For above example "5*5=25" is the result so, the "Quotient" is "5".If the value is large for example "506" of dividend and "8" of divisor means, first we...

The video describes the "Calculation of the surface area of the cone without a slant".

For people who are having problems with certain parts of geometry, this video will offer you advice on how to find a missing angle on the outside of a triangle when you are provided with the measurements of the other two angles in the triangle. Since the sum of the angles in a triangle is always 180 degrees, you should first take the sum of the other two angles and then subtract this from 180 in order to find the measurement of the missing angle in the triangle. Next, since there are also 180...

This video is a discourse about saltatory conduction in the neurons. According to the author, it begins with the opening of a gate on the membrane of one of the dendrites of a neuron, and positive charge enters through this gate. The positive charge spreads throughout the cell, and gets dissipated as it spreads, so that, by the time it reaches the Axon hillock of the neuron, it is left with very little potential. However, the potential which results from the simultaneous excitement of many...

In this tutorial the author shows how to factor a number. He says that factoring means to find all the smaller numbers which can be multiplied to obtain the original number. He says that the number one and the number it self are the factors of every number. Now to find the factor of a number he starts with 2 and tries to divide that number with 2. If he is able to divide it, it implies that 2 is a factor of that number. He now does this with each and every number between 1 and the number it...

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 you...

This video will show those who would like to learn more about math how to easily compare fractions with different denominators using a simple technique. You will be able to compare the fractions to each other by multiplying the numerator of each fraction with the denominator of the other, in a process called cross-multiplication. Keeping the numbers on the proper side of the equation, compare the two products which you receive from each cross multiplication and you will be able to compare the...

To find a vertical asymptote, you are trying to find values of x that produce 0 in the denominator but not in the numerator. If 0/0 occurs, that means you have a "hole" in the graph. A vertical asymptote is a place in the graph of infinite discontinuity, where the graph spikes off to positive or negative infinity. To find the vertical asymptote, set the denominator equal to zero and solve for x. Check that the values also do not give a zero in the nominator. If the values work, you have...

Struggling with math homework? An expert instructor from Khan Academy helps you work your way through the challenges of solving more difficult rational inequalities. Provides fantastic animated examples that demonstrate helpful tips, overcoming common problems with inequalities, and "simplifying" the problems of inequality simplification! Covers tricky complications such as swapping inequalities, understanding constraints, working with negative numbers, and working with zeros in equations....

A short video teaching you how to compare fractions. Starting with two fraction like three fourths and two over twelve. You cross multiply the denominator or the bottom number of three fourths which is 4 with the numerator or the top number of the second fraction which is 2. So the 8 that you come up with goes under the two twelfths. Now you do the same for the two fraction this time multiplying the denominator 12 with the numerator 3 coming up with 36. So now you have 36 under three...

This how-to video is about demonstrating the Leidenfrost effect with methyl alcohol and a penny.

This video teaches you to subtract mixed numbers with borrowing. Consider 2 mixed numbers. For example 8 and 2/7 and the other 5 and 4/5.You have to subtract 5 and 4/5 from 8 and 2/7. First you have to convert the fractions to their common denominator. To equate the denominators of these two fractions you have to multiply the first denominator with the numerator and the denominator of the second fraction and also multiply the numerator and denominator of the first fraction with the denominator...

In this video tutorial the instructor explains about the concepts of standard normal distribution and the empirical rule and how to use it to solve an exercise. He starts by explaining about standard normal deviation saying that in a standard normal deviation the value of mean is zero and the value of standard deviation is one. Now he draws the standard normal deviation by drawing a bell curve on an axis. Now he points the mean and standard deviations on it. Now using these concepts he goes on...

For anyone who is learning geometry and would like to learn or to review how to find the volume of a cone, this is the video for you to watch. The video provides you with both the simple formula for a cone as well as various examples which you can use to practice. The formula for finding the volume of a cone is 1/3 x pi x r^2 x h, where r is the radius of the base circle of the cone and h is the height of the cone.

In this tutorial the instructor shows how to solve linear and quadratic equations. It is a liner quadratic system where he shows a parabola and a straight line and he intends to solve the points where the line intersects the parabola. Now he uses comparison to compare the values of y in both the equation resulting in a equation in x. Now he shows the factors of the obtained polynomial equation and there by finding the values of x coordinates. Now he substitutes these values of x in the original...

Watch this video to learn how to convert improper fractions to mixed numbers. For example, follow these steps. First step is one fraction value. For example 7/3. Second step is divide the numerator by denominator means when 7 divide 3 you can get remainder as 1. Means 7 before value can multiply with the 6 so you can subtract 7-6=1 that is remainder. Multiplied value of 3 nothing but 2 is multiplication of the mixed numbers remainder take it as a numerator and denominator is always take it as...

For anyone who has ever struggled with long division, this video offers some tips on how to perform this seemingly daunting task with relative ease. The example provided in this video is a very useful one and by following the steps of this video, you will be able to do long division easily. Starting from the right side of the number which is being divided, add 0's as place holders until you arrive at a number which can be divided by the number you want to divide by. Perform this one simple...

This is an educational video usually for college students or maybe even some high school students. This video explains to us how to calculate our cumulative grade point average. The main character in this video is Colleen who is a Registration Assistant. This video is mainly concerned with the students at the specific university that Colleen attends, however, all students who are graded can use this to help calculate their GPA. Although Colleen goes into a rather lengthy explanation of GPA,...
