WebSep 30, 2024 · Trigonometric equations Formula’s. 1. sinx = 0 s i n x = 0 implies x =nπ x = n π, where n is any integer . 2. cosx =0 c o s x = 0 implies x = (2n+1)(π/2) x = ( 2 n + 1) ( π / 2) . sinx = siny s i n x = s i n y then x = nπ+(−1)ny x = n π + ( − 1) n y where n is any integer . cosx =cosy c o s x = c o s y then x =2nπ+y x = 2 ... WebSo it looks more complicated. But there's a nice trick we can do here, and that again is going back to some trigonometry. Specifically the following trigonometric identity. Which says that if you take sine of A-B, then that's equivalent to sine(a)cosine(b)- cosine(a)sine(b). Hopefully I got that ordering correct.
