Question

How do i find the rest of the trig functions if

Tan X = undefinied

and Sin X > 0

Answer 1

Well, if you know that sin x > 0, you automatically know you are in quadrants I and II. and if tan x = undefined, since tan x = y/x, then x must be 0 so you are looking at either 90 degrees or 270 degrees. and it must be 90 degrees because it has to have a positive sin (sin 90 = 1). You should be able to find the trig functions now. With these kinds of problems you want to extract as much information that is given as possible. (:
