Ok this is the product rule with respect to cosign and sign which I’m going to show you and we get started to get to my menu you have to press second alpha and enter the letters i n d e x and then press alpha again to put the eight and the open and closed parenthesis press enter and you are into my menu you scroll up or where ever you want but I want to dot product rule right now so were going to do that one I give you the formula write all this stuff down on your paper or test whatever it’s always good to write use all parenthesis lot of parenthesis and you have to press alpha before you enter anything in my entry lines here and you have to enter it in this form here parenthesis with a times sign and parenthesis so were going to press alpha left parenthesis and put a function in here press the gold key for cosign five time x close off the parenthesis times sign add the other parenthesis and put gold key sign five times x cubed and then press enter. I always show you what you’ve entered so you can change it if you want give you the option there on the next screen. I say it’s ok. I show you what f of x is and g of x is and then you apply it to the formula and keep working the problem write down everything you see on your paper and you get a hundred percent on this problem and here’s the answer five x squared cosign of five x times cosign of five x and then minus five sign of five x sign of five see you write this down hundred percent on your paper.

I’m going to do a video on a product rule with ya know pretty hard one variable function to get started we’ll press second alpha to put the i n d e x in here in my menu and then we’ll press alpha and get put in the eight and the open and closed parenthesis press enter and you are into the menu. I’m at the product rule here’ but you can see number of many many things in calculus that will help you pass calculus and learning calculus if you want to go that far we’re going to do product rule right now. I show you the formula taking f prime of f of x function times g of x and then f of x time g prime of x and we’ll enter our function you have to press alpha before you put anything in my entry lines here we’re going to put it in this form here parenthesis with a times sign in between. So we press alpha put the left parentheses in and put three times x minus two close off the parentheses put the times sign and let’s go five times x cubed minus x squared plus one now you notice that anytime you have you see a any function in a test or on homework where you have two functions multiplied together you use the product rule if there was a division sign here you’d be using the quotient rule ah be hip to that and i always show you what you’ve entered so you can change it if you’ve made a mistake but that’s what we want and I show you where f what f of x is your choice for that is and of course the choice for g of x and we work the formula and here’s the answer here all of these are added together and here’s your answer pretty neat huh? all my programs are step by step like this show you exactly how to do it so wouldn’t take you long to learn it if if you knew it like this.
