Hello everyone. This is Tom from everystepcalculus.com.

I’m going to demonstrate the Chain Rule right now.

Let’s do it. Index eight to get to my menu for calculus.

And we’re going to

scroll down to the C section. They’re all alphabetical.

Here’s chain rule here.

And I gave you a choice of what kind

problems you’re gonna do. Sine, Cosine, Tangent, etc.

Or given Y, etc.

Here’s the, in parentheses, with an exponent.

And here’s the square root of something. I’m going to do number 2 here.

Press alpha before you

put anything in these entry lines here.

Alpha first and the left parentheses which it gives you up here for example.

And we’re going to 5 times x squared

plus 7 to the fifth power

I always show you what you entered. You can change it if you want.

We’re going to differentiate that.

I say it’s okay. Here’s the formula here for chain rule.

and I go through the steps for you. It’s kinda like U-Subsitution

in a way for differentiation. U-Subsitution is really for integrals.

So after we put the terms into the into the formula. Mark everything down in your paper you see it.

Here’s the derivative of g of x

which is 10 times X

and keep writing and here’s the answer.

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

ex 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’st he 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. Enjoy my programs and pass calculus.
