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?
