WebNov 12, 2015 · 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 answered Nov 12, 2015 at 13:58 PM 2Ring 4,516 17 26 Add a comment 1 Webc = a√2. Therefore, both the sine and cosine of 45° equal 1/√2 which may also be written √2 / 2. Next consider 30° and 60° angles. of the sides are 1 : √3 : 2. It follows that sin 30° = cos 60° = 1/2, and sin 60° = cos 30° = √3 / 2. These findings are …
