Chain Rule, If you see in a given problem, a function

with a square root sign, or a function enclosed in parenthesis where that function is taken

to a higher power in other words has an exponent, or a trig function such as sin, cosine, or

tangent where there is something more than an x in the parenthesis of that trig function,

you are using the chain rule.

To get to my menu You have to press second alpha on the Titanium

to enter letters in the home screen, and then you enter the letters i n d e x

press alpha again and enter the eight and the closed parenthesis

Press ENTER and you're into my menu

You choose "chain rule" by scrolling down to it, or pressing the number before it, in

this case the number six

Then press ENTER

You are given three things to choose from here

One, Anything enclosed in parenthesis to a power

Two, If you are already given u and f of x And Three, the trig functions with something

more than an x involved

I'm demonstrating the third option in this video, the trig function

Enter your trig function

Press alpha first, then the second button, I'm going to do tangent

Three times x squared

I show you what you've entered You can change it if you want

I say it's ok

You write all of this down on your paper or homework

Here's the formula Here's the choice for u

Here's what f of u And you'll notice one over cosine u squared

This is an identity for secant squared, the derivative of tan of u

Identities, derivatives and integrals of trig functions can all be obtained by going to

trig d d x in my main menu And the next screen is the step by step answer

Pretty neat huh? EveryStepCalculus.com
