Exam-Specific Questions

[cosine]

Seems fine to me. What calculator are you using?

I have the TI-89 Titanium vs. TI-Nspire CX CAS

It just gives it to me in decimals and Im not sure why.. :/

First off, I have the Classpad 330 so this might be a little different to your calculator. I'm assuming you're graphing the function and finding the x-intercepts from there? If you are, try this instead:

Go to the "Main" function of the calculator and define the function as f(x). Then, let f(x) = 0 and restrict the domain using the | key and solve for x.

Apologies for being a noob, but how do I define a function on the calculator?

Many thanks for the help, bills

For TI-nspire, Define f(x)=function

[cosine]

Thanks guys, but how do I get the derivative of |sin(x)(sin(x)-cos(x)|??
