The form you should use may be given to you in a question, but if not, any one will do. If in doubt, \(k\cos (x - \alpha )\) usually works. These worked examples show the processes you'll need to go ...

Solve the equation \(5\sin 2x^\circ + 7\cos x^\circ = 0\) for \(0^\circ \le x^\circ \le 360^\circ\) Which gives us solutions of \(90^\circ ,224.4^\circ ,270^\circ ,315.6^\circ\) There are two more ...

Trigonometric functions are often used in embedded systems. Motor drivecontrol applications such as the Park Transform, Clarke Transform, andPWMgeneration use trigonometric functions extensively.
