Mathematicians once turned up their noses at imaginary numbers. But complex analysis actually simplifies math and physics.

Mathematicians had long thought that using trigonometry to prove the theorem was unworkable, given that the fundamental ...

Solve \(\sqrt 3 \cos x + \sin x = \sqrt 2\), for \(0 \le x \le 2\pi\). First of all we need to put \(\sqrt 3 \cos x + \sin x\) into the form \(k\cos (x - \alpha ...
