Find theta by cos(theta) and sin(theta).

I have values of cos(theta) and sin(theta) and I want to calculate the value of theta. Because of the return value of asind is from -pi/2 to pi/2, I get two different values when I use acosd(cos(theta)) and asind(sin(theta)). what should I do?

theta=37;

atan2d(sind(theta),cosd(theta))

ans = 37
