Core 2 Calculator question.

I have just been doing some trig questions and I was wondering if on those graphical calculators you can find all the intersections points on Cosine and sine graphs. I can solve these manually but of course it would be good for checking. It would be greatly appreciated if anyone can shed some light on this before I go out and buy one.

Yes, you can.

What in the world do you mean by intersection points?

Say, for example, tan2x=3 in the range 0<x<360 . If you drew y=tan2x and y=3 you would see that there would be points where the two intersect
