Webb15 feb. 2016 · The formula for sin(nk) is easily derivable with binomial expansion: sin(nk) = e − nki − enki 2i = cnk − c − nk 2 The solution is very similar to the cosine, with the exception that complex numbers will appear more than one may like. Also, there is no Chebyshev polynomial for sine as far as I have seen. http://tkrajina.github.io/Salabahteri/trigonometrija.pdf

Webb1 Answer. Let's instead prove the sum formula: sin ( α) = sin ( α − β) cos ( β) + sin ( β) cos ( α − β). To do this, explain why the first summand on the right equals C D / A B, while the second summand on the right equals B P / A B (hint: use similar triangles!). Combining these two gives you the sum formula. WebbTrigonometric Identities are useful whenever trigonometric functions are involved in an expression or an equation.
