Tìm nguyên hàm:

[TEX]I=\int \frac{{sin}^{3}x-sinx}{cos2x}dx[/TEX]

[TEX]I_1=\int \frac{dx}{\sqrt[5]{{cos}^{7}x{sin}^{3}x}}dx[/TEX]
[TEX]I=\int \frac{cos^2xdcosx}{1-2cos^2x}[/TEX]

[TEX]I_1=\int \frac{dx}{\sqrt[5]{cos^{10}xtan^3x}}=\int \frac{dx}{cos^2x\sqrt[5]{tan^3x}}=\int \frac{dtanx}{\sqrt[5]{tan^3x}}[/TEX]
