Setting z = x, y = 0 and using the identity theorem we get f (z) = c1 ez + (1 − c1 )e−z + id d ∈ R.

I know what you did last summer cos(2x) = cos 2 (x) – sin 2 (x) = 1 – 2 sin 2 (x) = 2 cos 2 (x) – 1 Half-Angle Identities The above identities can be re-stated by squaring each side and doubling all of the angle measures. It is called the cos double angle identity and used as a formula in trigonometric mathematics. It can written mathematically in two forms. The several cos ⁡ 2 x \cos 2x cos 2 x definitions can be derived by using the Pythagorean theorem and tan ⁡ x = sin ⁡ x cos ⁡ x.
