see here. it tells you how to determine the period of tangent and cotangent
Determine the period of f(x) = 3cot2x.
This is going to be on my no calculator final tomorrow but I have no idea how to do it without a calculator? What happens if the question changes to csc or sec? Or if the number infront of the x changes? How would you do it then?
Can someone please explain it to be, I really need to how to do it cause it's worth about 4 marks!
