WebNov 12, 2015 · The identity you seem to be unaware of is known as Euler's formula: e i x = cos x + i sin x FWIW, that formula is valid for complex x as well as real x. Substitution of − x gives: e − i x = cos ( − x) + i sin ( − x) = cos x − i sin x Thus, e i x + e − i x = 2 cos x and e i x − e − i x = 2 i sin x Share Cite Follow edited Nov 12, 2015 at 14:05
