Hi, it looks like you're using AdBlock : (. Sep 20, 2020 at 19:44.3, 17 Prove that 𝑠𝑖𝑛〖5𝑥 + 𝑠𝑖𝑛3𝑥 〗/𝑐𝑜𝑠〖5𝑥 + 𝑐𝑜𝑠3𝑥 〗 = tan 4x Solving L. sin〖5x + 〖sin x − 〗2sin3x 〗/𝑐𝑜𝑠〖5x − 𝑐𝑜𝑠x 〗 = 〖 (𝐬𝐢𝐧〗〖𝟓𝐱 + 〖𝐬𝐢𝐧 𝐱) −
Solution. Hence sin5(x) + cos5(x) = 1. Use one of the substitutions: u=sinx " " OR " " u=cosx int sin^5x cos^3x dx = int sin^5xcos^2xcosx dx = int sin^5x (1-sin^2x)cosx dx = int sin^5x cosx dx - int sin^7xcosx dx Substitute u = sinx to get = 1/6 sin^6x - 1/8 sin^8x +C OR int sin^5x
Transcript. So, x = π 2 + 2nπ x = π 2 + 2 n π or x = 2mπ x = 2 m π. First, send every thing to one side.S.snoitulos pets-yb-pets htiw revlos htam eerf ruo gnisu smelborp htam ruoy evloS
