This week we learned the chain rule and stuff. Its basically the same as the power rule just used at different times with one difference. We also learned the general power rule, which is a form of chain rule.

The chain rule is used when you have two things going on. For example:

(x^2+x+3)^2

First step is like normal, you would move the exponent to the front.

2(x^2+x+3)^2

Next, you subtract one from the original exponent to form the new exponent.

2(x^2+x+3)

The next step is to take the derivative of the inside and multiply by it.

2(x^2+x+3)(2x+1)

Then you factor/simplify if you can, but this one is as simplified as it needs to be.

So, that's about it for what we learned this week.
