Microsoft Math 3.0
cos( arctan(-((1)/(3)))+ arccos(-((3)/(5))))

If we had to find the exact value of the expression how would you use Microsoft Math to solve it?

Or any Trig problem that is not an equation for that matter.

Okay, I think I now get what MS Math is, but if you want an exact expression why aren't you doing it by hand? Not that there even is an exact expression for this...

Is your actual question about how to use MS Math to calculate it?
