Question: Find value. Assume that all angles are in Quadrant 1.
Suppose that arcsin(3/5) = theta, that is theta is the angle whose sine is 3/5. Since the angles are all in the first quadrant you can draw a representative right triangle.
Use the theorem of pythagoras to find the third side of the triangle and then you can read the cotangent of theta off the diagram.Cheers,
