Given sin theta= 2/3 and cos theta= sqrt 5/3, how do I find csc theta? Click to expand... I'm going to use @ for "theta"...much easier to type. The basic definitions for the trig functions tell us that tan @ = sin @ / cos @, AND cot @ = cos @ / sin @ You are given sin @ and cos @..... cot @ = cos @ / sin @ Substitute the values given, and do the arithmetic. For the second part, csc @ = 1 / sin @ You are given sin @....
