In this video I’m going to do the chain rule, I’m sure you know how my fabulous program works on the titanium calculator. We have to enter index 8 into the calculators home screen, you can do that by going second alpha, you can see second alpha highlighted here so you can put the letters in “index” and then you have to press alpha 8 to get to numbers in parenthesis and then is my menu that comes up. Menu is quite long all the way down here,all alphabetical and you can choose what you want; product rule, quotient rule, limits whatever you might need, not everything that you need but most of the stuff is on tests, I took these off of my tests and I programmed them. We got to do the chain rule so we can either scroll down to it or you can press the number in front of it, I’m going to press 5 and go to the number and we are going to put two systems U and g of x, I’m going to use the g of x system. And we have to press alpha and put in function, let’s try it 5Xx2+6 close parenthesis to the 8 power, shows you what you entered 5X squared to 6 to the 8th power, find the derivative of that, always give you a chance to change the *2:08* mistake, doesn’t look right or something, now we’re into the problem, here is the fundament for the chain rule *2:16*, you write this on your paper or homework. f[g<x>] is U over 8 and f1[g<x>] is the first derivative of x which is shown here and g(x) is the *2:36* portion 5X2+6 and the fist derivative of that is 10 to the X, and we put it together *2:46*, we have to substitute 5X2 for U, so we do that and here is *3:02* and then we can go back and do another problem or whatever. Pretty neat huh, I’ll tell you everystepcalculus.com and check it out, my website.
