### What is the formula for double angle formula?

Double Angle Formulae. sin (A + B) = sinAcosB + cosAsinB. Replacing B by A in the above formula becomes: sin (2A) = sinAcosA + cosAsinA. so: sin2A = 2sinAcosA. similarly: cos2A = cos 2 A - sin 2 A. Replacing cos 2 A by 1 - sin 2 A in the above formula gives: cos2A = 1 - 2sin 2 A.

### How to derive the formula for angle addition without complex numbers?

These formulas can be simply derived using complex exponentials and the Euler formula as follows. Equating real and imaginary parts then gives (1) and (3), and (2) and (4) follow immediately by substituting for . The angle addition formulas can also be derived purely algebraically without the use of complex numbers.
