This video tells us the method of interpreting derivatives of marginal cost and revenue. If C(x) is the cost of producing x units of a product, C(400) would be the cost to produce 400 units. Now marginal cost is the cost of producing one unit which is equal to the derivative of the cost function or C'(400) which is equal to limit of h tends to zero or lim h->0 [lim(400+h)-lim(400)]/h which is approximately equal to [lim(401)-lim(400)]/1. Similarly, if R(x) is your revenue function, marginal r...

JustMathTutoring This video shows the procedure of finding derivatives using the Chain Rule. The Chain Rule states that the derivative of a composition of functions is the derivative of the outside function evaluated at the inside multiplied by the derivative of the inside. This can be stated as if h(x) = f[g(x)] then h'(x)=f'[g(x)]g'(x). This is explained by two examples. In the first example we find the derivative of the sine of square of 'x'. We take the derivative of sine at square of 'x'...

Learn how to compute derviatives from this web channel devoted to educational shows and resources for schools. Annenberg Media brings you an interesting lecture that combines history and math. Compute derivatives.

The relationship and the definition of derivatives and anti-derivatives is described in this video. First, consider a function F(x)=x^3-5x+2 and another with small 'f', f(x)=3x-5. f(x) here is the derivative of F(x). However, on the contrary, F(x) is said to be the anti-derivative of f(x). There is a catch though; even though F(x) has only one derivative in the form of f(x), f(x) here has more than one anti-derivative. This is because f(x)'s anti-derivatives are of the form F(x)=x^3-5x+c, whe...

Last week's challenge brought up a good question (thanks Lisa) regarding the functionality of the Official Scrabble Players Dictionary, 4th Edition, both online and in print form. The word TACTICAL was the answer to the first puzzle in that challenge, but when you search for the word directly in the print version, it can't be found. Likewise, when you search the online dictionary on Hasbro's site, you won't find it either. Go ahead, try it. You won't find it looking for TACTICAL specifically.

Chlorine gas is a very useful oxidant, which was first introduced as a toxic weapon by the German Army. Even today, it's still used as a weapon, most recently in the Iraq War by insurgents. But chlorine gas has more useful (and less lethal) applications, and if you want to learn how to make some at home, NurdRage has the answers.

In this video tutorial, viewers learn how to define an indefinite integral in calculus. Finding the anti-derivatives of a function is called anti-differentiation. The f(x) is the derivative of F(x), while F(x) is the anti-derivative of f(x). If F(x) is the anti-derivative of f(x), then F(x) + c are all anti-derivatives of f(x). This video is very descriptive and clearly explains all the functions of this mathematical function. This video will benefit those viewers who are students, and are in...

The guy first gives the definition of differential equations. He explains that a differential equation is an equation that contains the derivatives of an unknown function. He then gives some examples of differential equation and explains what the equation's order means. After that he gives an example on how to solve a simple equation. He calculates it and gives examples of graphs. Then he explains what a general solution is and how to narrow down the number of solutions using data from the pr...

Cytochrome P450 (P450s) are proteins found in nearly all living organisms, which play roles that range from producing essential compounds and hormones to metabolizing drugs and toxins. We use some of the compounds synthesized by P450 in plants as medical treatments, but the slow growth and limited supply of these plants have put the drugs' availability in jeopardy and jacked up prices.

Forget jello— start using agar (aka agar-agar) in place of gelatin. Agar is a thickening agent, just like gelatin, than can be used in recipes for soups, jellies, ice cream and more! Jeff Potter has the 411 on agar uses. It's a great choice when preparing dishes for vegetarians, as it's a seaweed-based product with no animal derivatives whatsoever. Give it a try with two creative recipes from Jeff— Chocolate Panna Cotta and Screwdriver Jellies. Use agar (aka agar-agar) for dessert recipes in ...
