Integrating cos 4
Nettet8. mar. 2024 · Integral of cos (4x) formula. The formula of integral of cos contains integral sign, coefficient of integration and the function as sine. It is denoted by ∫ (cos (4x))dx. In mathematical form, the integral of cos (4x) is: ∫ cos ( 4 x) d x = sin ( 4 x) 4 + c. Where c is any constant involved, dx is the coefficient of integration and ∫ is ... NettetIntegrating Products and Powers of tan x and sec x. Before discussing the integration of products and powers of tanx and secx, it is useful to recall the integrals involving tanx and secx we have already learned: ∫sec2xdx = tanx + C. ∫secxtanxdx = secx + C. ∫tanxdx = ln secx + C. ∫secxdx = ln secx + tanx + C.
