In this 8lesson series of lessons, Professor Burger will introduce you to the most common rules for differentiation: the power rule, the product rule, the quotient rule, and the chain rule. In addition to coming to understand each of these different techniques for finding derivatives, we'll also work with problems that require us to use multiple different techniques in order to find a function's derivative.
The power rule states that if N is a rational number, then the function f ( x) = x^N is differentiable and f ?( x) = Nx^(N?1). We'll look at how the power rule works, examine a quick proof of the general case of the power rule, and look at a few uses and extensions of the power rule. Two extensions of the power rule are the constant multiple rule and the sum rule. The constant multiple rule says that for any constant, c, the derivative of c times differentiable function f(x) is the same as f'(x) times c. The sum rule states that for two differentiable functions, f(x) and g(x), the derivative of their sum is the same as the sum of their derivatives, or f'(x) + g'(x) = [f(x) + g(x)]'
The derivative of a product or quotient of two functions is not necessarily equal to the product or quotient of the two derivatives. The product rule states that if p(x) = f(x) * g(x), where f and g are differentiable functions, then p is differentiable and p'(x) = f(x)g'(x) + g(x)f'(X). The quotient rule states that if q( x) = f ( x) / g( x) , where f and g are differentiable functions, then q is differentiable except where g( x) = 0 and q'(x) = [g(x)f'(x)  f(x)g'(x)] / [g(x)^2]
A composite function is made up of layers of functions inside of functions. Some techniques of differentiation become very cumbersome when applied to composite functions. The chain rule states that if f ( x) = g(h( x)) , where g and h are differentiable functions, then f is differentiable and f ?( x) = g?(h( x)) ? h?( x) .

Calculus: Uses of the Power Rule
This lesson covers the power rule, the sum rule, and the constant multiple rule (all related to differentiation). Through this video, you will learn how to evaluate derivatives without using the definition as the method. The power rule is the shortcut used for finding a derivative of any variable raised to the power of a rational exponent. The constant multiple rule asserts that the derivative of any function times a constant is the same as the derivative of that function times that exponent. The sum rule shows that the derivative of the sum of two functions is equal to the sum of the derivatives of both functions.

Calculus: The Product Rule
In this lesson, we learn about taking the derivatives of products and applying the product rule of differentiation. The derivative of the product of two differentiable functions is NOT equal to the product of the derivatives of both functions. Instead, you must learn and apply the product rule to calculate the derivative of the product of two functions. The product rule states that the derivative of f(x)*g(x) = f(x)* derivative of g(x) + g(x)* derivative of f(x).

Calculus: The Quotient Rule
In this lesson, we learn about taking the derivatives of quotients and applying the quotient rule of differentiation. The derivative of the quotient of two differentiable functions does not necessarily exist and is not necessarily equal to the quotient of the derivatives of both functions. Instead, you must learn and apply the quotient rule to calculate the derivative of the quotient of two functions. The quotient rule states that, when f(x) and g(x) are both differentiable and g(x) does not equal 0, the derivative of f(x)/g(x) = [g(x)* derivative of f(x)  f(x)* derivative of g(x)]/g(x)^2

Calculus: Using the Chain Rule
The chain rule is a technique used for differentiating composite functions. In this lesson, you will learn the chain rule as well has how to apply it. Professor Burger will carefully walk through mistakes to avoid when using the chain rule as well as the correct way to use the chain rule in conjunction with the product rule for differentiation. The chain rule states that the derivative of g(h(x)), where g(x) and h(x) are differentiable functions, is the derivative of g(h(x)) times the derivative of h(x).

ARE NOT LIKE ONIONS!
thank you! saved me on my midterm!!!!
There are a few things I disagree with though a bit. One of which is the chanting deal. All you really need to do for product and quotient rules is memorize 2 letters and a ' symbol with them.
product rule = fg' + gf' (where you make f = to a function and g = to a function)
quotient rule = (gf'  fg') / g^2.
Never been a huge fan of "top times bottom" chants and all that stuff. Also, it would be nice if Mr. Burger simplified some of the problems sometimes when he gets to the end. It's nice to say well we're done, but technically you're not unless multiplying everything out would be ridiculously complicated.
At any rate though, his teaching style is still very effective and helps to keep me focused when I'm drifting in my calculus book.
