Determine the period of the function:

f(x) = sin(x)

Hence, period of sin{x} is 1. Solution : Inverse trigonometric function tan⁻¹x is one one function in [1,1] and tanx is a periodic function with period π in R.

Step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
