What Is The Integration Of Tan 2x Solution Quora
Rather, integral of (u^2)du = (u^3)/3 c In (tan^2)x your 1st mistake is not writing dx Note that dx is NOT always du!!!!! Integral of tan^2x, solution playlist page http//wwwblackpenredpencom/math/Calculushtmltrig integrals, trigonometric integrals, integral of sin(x), integIntegral of sec^2 (x) \square!
Integral udv= uvintegral vdu=logxtanx integral logxsec^2xdx so integral tanx/x dx= logxtanx integral logx sec^2xdxA now consider the second term in the rhs integal logx sec^2x dx, again applying by parts technique let u= logx , du= 1/xdx integral sec^2x dx= dv , v= tanx on integrating so this becomes logxtanx integraltanx/x dx What I get is let u = sin x then or du = cos x dx So Rather than saying u = sin x, use u = 2x instead Just expand tan u into This integral is much easier to solve Expanding sin 2x and cos 2x in terms of sin x and cos x just makes things more complicatedLet mathI = \int e^{x}tan(x) \, dx \tag1/math Using integration by parts It does not matter which of mathe^x /math and mathtan(x)/math you choose to integrate for the first integration by parts, but which you ever you choose you must
