Press enter and you’re into my menu. you have many options here for passing tests and homework in my menu here many things integration by parts integration by parts inflection points and graphing by hand uh… e to the x integrals we’re going to scroll up to dot product gonna enter our first vector _a you have to press alpha before you enter anything in my entry lines alpha eight alpha minus three alpha minus five _b vector alpha seven
alpha nine, alpha two. I show you what you’ve entered case you made a mistake you can change it. I say it’s okay. this is the menu for all of my vectors. uh… many things here projection of a and b all kinds of things that you’re going to be calculus two probably and we’re going to scroll down to _v section here and find dot product. Write everything down on your paper exactly as you see it and gives you the total answer here. Pretty neat huh? everystepcalculus.com enjoy my programs and pass calculus.
