		<title>3 Free Calculus Videos</title>
		<description><![CDATA[Get Your Free Calculus Videos
From: Dave McMahon
1:31 PM
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) [...]]]></description>

		<title>Chain Rule</title>
		<description><![CDATA[The chain rule allows us to compute the derivative of a composite function. In other words suppose that:

for some functions f and g. For example:

In this case we can identify:

How do you compute the derivative in this case? The chain rule tells us that we compute the derivative in the following way:

Let&#8217;s compute some examples. [...]]]></description>

		<title>Integrals trig functions</title>
		<description><![CDATA[In this video integrals involving powers of trig functions are illustrated. Usually this kind of integration involves some form of either u substitution or forces us to call upon various trig identities. See our earlier post on trig integrals for more discussion and examples.

		<title>Implicit Differentiation</title>
		<description><![CDATA[
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 [...]]]></description>

		<title>Trig Integrals</title>
		<description><![CDATA[Doing trig integrals is usually pretty simple. This is because of the cyclic nature of the derivatives of trig functions. Let&#8217;s recall that:


From here we can write down their anti-derivatives:

The minus sign comes about because we integrated the derivative of cos x to get this result. That is

but this was equal to minus sin x. [...]]]></description>

		<title>Doing an integral using u substitution example</title>
		<description><![CDATA[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&#8217;ll see in a moment that this integral evaluates to an inverse tangent. We&#8217;re going to use two steps [...]]]></description>

		<title>Solving Calculus Limits Example</title>
		<description><![CDATA[Computing calculus limits often involves using an algebraic trick. In this post we&#8217;ll look at the example of a ratio of two polynomials. In this case you&#8217;ll want to factor the polynomials so that you can eliminate one of the troubling terms. Here&#8217;s an example:

If you just set x = 2, you get 0/0. However [...]]]></description>

		<title>Integration by parts with limits</title>
		<description><![CDATA[Integration by parts with limits is really the same as integration by parts with indefinite integrals until the very end of your calculation. Let’s see how to do integration by parts with limits with an example:
 
Its always a good idea to start out writing the integration by parts formula:

For now, we can simply ignore [...]]]></description>
