Please Subscribe here, thank you!!! https://goo.gl/JQ8NysSolving the Differential Equation dy/dx = tan^2(x + y) You can not integrate tan 2 x but you can integrate sec 2 x Since sec 2 x = 1 + tan 2 x Then tan 2 x = sec 2 x-1 so the intragral of tan 2 x dx = the integral of (sec 2 x-1) dx = intrgral of sec 2 x dx + integral of 1 dx = tanx-x +C [math]I = \int x \ tan^2(x) dx[/math] Taking advantage of the fact that [math]tan^2(x) = sec^2(x) - 1[/math], [math]I = \int \left[ x \ sec^2(x) - x \right] dx[/math \int tan^{2}\left(x\right)dx. en.
