2012-02-12 · sin(x)sec(x) - 2sin(x) = 0. sin(x)sec(x) = 2sin(x) sec(x) = 2. Taking the reciprocal of each side, cos(x) = 1/2. Draw a 30-60-90 triangle; the side adjacent to the 60-degree angle, and the hypotenuse, are in a ratio of 1/2. 60 degrees (or pi/3 radians) fits that.

Since $ \ x = 2 \sin \theta \ $, it follows that $$ \sin \theta = \displaystyle{ x \over 2} = \displaystyle{ opposite \over hypotenuse } $$ and $$ \theta = \arcsin \Big(\displaystyle \frac{x}{2} \Big) $$ Using the given right triangle and the Pythagorean Theorem, we can determine any trig value of $ \theta $.
