From this formula expressions can be obtained for sin x and cos x in terms of the exponential functions of a purely imaginary argument: These equations, which also are called Euler’s formulas, can be used to determine the values of cos z and sin z for complex z. For purely imaginary va...
Hint: Take $5\theta $ as $3\theta +2\theta $. Now use trigonometry identity of $\sin \left( A+B \right),\sin 3\theta ,\cos 3\theta ,\sin 2\theta ,\cos 2\theta $ to solve it further and get the value of $\sin 5\theta $ in terms of $\...
