Drawing trig graphs on the Casio ClassPad 330 to 'Exact Values'

[Sam_95]

Wondering how one goes about doing this. When I try to draw cos, sin and tan graphs on the calculator and try to find x values to just gives me numbers like 1.53242342332 etc etc.

Does anyone know how to get this to exact radians/degrees quickly?

I have a ti cas cx, and for mine you have to change the settings for it to be in radian or degree mode, im pretty sure it can only be in one mode at a time, meaning all answers are given in that format independent of the question

So i'd assume you would have to either set it to degree or radian mode on your calc too

I'm also interested >->.

No matter whether its in RAD or DEG, it still doesn't give me exact values. Anyone have any clue?

I tried to find a way to do it but i cant seem to find a way..!
do you know how to figure it out by hand ?

Hmm.. I'm not sure how to either..

If you cannot do it quickly by hand, then you can always use the solve function in 'main' and you can restrict the domain such that it is written like this:

the symbols are found in the OPTN tab down the bottom of mth or 2D



edit: that looks more complicated than it really is.. don't worry though, I just wanted to use an example that showed multiple translations and whatnot

I put exactly what you said into main and solved under a restricted domain and still got a decimal answer
