How would I have to write this code into MATlab?

Trigonometric functions: sin x = sigma^infinity_n = 0 (-1)^n/(2n + 1)! x^2n + 1 = x - x^3/3! + x^5/5! -... for all x cos x = sigma^infinity_n = 0 (-1)^n/(2n)! x^2n = 1 - x^2/2! + x^4/4! -... for all x tan x = sigma^infinity_n = 1 B_2n(-4)^n(1 - 4^n)/(2n)! x^2n - 1 = x + x^3/3 + 2x^5/15 +... for |x|
