Quadratic Equations

Here is a good video on solving quadratic equations.

Integrating by Parts Twice

Hey-
I was browsing math videos on You Tube and found this nicely done presentation on doing integration by parts twice. Check it out.

Hi,
My name is Dave and I’ve made a few calculus tutorial videos I’d like to send you.
If you’re already a pro, then you won’t need these… but if you’re just learning calculus then make sure you enter your email below (or to the right side) [...]

Implicit Differentiation

Implicit differentiation is a technique used to compute a derivative when a function y = f(x) is given indirectly by an equation that relates x and y. For example suppose that you are given:

The equation must be solved for y to obtain an explicit solution, and in this case there are two solutions. The procedure [...]

Doing an integral using u substitution example

Solving an integral with u substitution brings an integral into elementary form through a change of variable technique. In this example we consider a problem where it may not be obvious how to apply the method. Consider:

We’ll see in a moment that this integral evaluates to an inverse tangent. We’re going to use two steps [...]

Computing calculus limits using L’Hopitals rule

The other day I was browsing my old calculus book and came across a limit often presented early in textbooks, sin(x) divided by x. Here is the limit:

Well its pretty easy to see this is a problematic expression. As x goes to 0 we have 0/0. If you’re just learning basic calculus, you’re probably at [...]
