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. Go to my site buy my programs and pass calculus.
