tanx5dx \int \sqrt[5]{\tan x} d x

Full solution

Q. tanx5dx \int \sqrt[5]{\tan x} d x
  1. Identify integral: Identify the integral to be solved.\newlineWe need to solve (tan(x)15)dx\int(\tan(x)^{\frac{1}{5}}) \, dx.
  2. Apply substitution: Apply substitution if possible.\newlineLet u=tan(x)u = \tan(x), then du=sec2(x)dxdu = \sec^2(x) dx.
  3. Rewrite in terms of u: Rewrite the integral in terms of u.\newline(u15)(1cos2(x))dx\int(u^{\frac{1}{5}}) \cdot (\frac{1}{\cos^2(x)}) dx, but we need to express 1cos2(x)\frac{1}{\cos^2(x)} in terms of u.
