Hi I’m Tom the calculus and physics guy that programs the TI-89 Titanium calculator uh… today we’re going to do the curl on the titanium and show you step by step how to do the curl enjoy my programs at EveryStepCalculus.com the first thing you enter is index eight close parentheses in my programs the home screen and uh…up will come the menu and you can see where you can scroll down for many many other things which then again takes you to other many many things so what were going to do the curl today I’m going to press number 8 or you can press the number of the alphabet before it and you notice we have instructions curl definition or do curl problem uh… whatever your choice is there were going to do the problem quickly give you the choice of the P Q R or the M N P variables

I’m going to use the P Q R system and here it is in the cartesian form I J K or the vector form with the two arrows on the sides and the P Q R inside of the arrows that’s called the vector form and the first function we’re going to put in for P and press alpha first uh… y times z squared press it twice 2nd function is alpha you have to press alpha first as I just said uh… x times y and the next example is alpha y squared times z it shows you what you’ve entered in case you want to change it or you made a mistake that’s good also shows you the cartesian system in case you need to write that down you can okay or change it this will say its okay here’s the formula for the curl the matrix system uh… you’re doing cross product of the functions those little indications before the letters are partial signs and that’s a partial of r with respect to the partial of y minus partial q with prospective partial of z etcetera and here’s the actual calculations and there’s the curl in vector form here’s the curl in the cartesian form next thing it gives you what you want to go conservative or you wanna find the divergence or you want to compute the curl at points or you want to compute the divergence at points or new variables or what pretty neat huh?
