Does anyone have the Heffernan 2007 CAS exam 2 solutions?

Kekeke.

Also, I'm not sure how to put limits in my CAS [TI-89 Titanium] (e.g. if I wanted it to be from x->a and solve...)

Thanks in advance

Collin Li:
Dunno how CAS functions, but try graphing the function, f(x), and observe what happens as x -> a

kingmar:
I did CAS 1/2 last year. I <3 solve!!!

Anyway, to do limits:

Press F3. Choose Option 3, the limit.

Then, input your function, followed by the parameter and what it's approaching.

So, if I wanted the derivative of something, I could say:

limit(6x+3h+2,h,0)

This means that I want to find the limit of 6x+3h+2 as h approaches 0. (6x+2).

JL_91:
yes, i have a copy of those solutions. how do you want me to send it to you? with your limits question, if you mean that you want to solve f(x) for a certain domain, the TI89 way is to type, e.g. Solve(f(x)=0 |x>a and x<b). you can't put a<x<b as your domain after the 'given' sign, you have to do each separately. if you meant that you want to find the limit of an equation as x->a, go to F3:Calc (the calculus menu in your home screen), choose 3:limit( and put in e.g. limit(8x+1,x,5) and you'll get the limit as x->5. hope that helps, i don't know what CAS you're using tho

Cheers, that worked.

Do you have msn? That usually seems to work :)

Thanks for the domain stuff, I do use T1-89 so thanks.
