não consegui entender poderiam explicar

olá

\(\int \frac{\frac{27}{8}*tg^{3}x}{(9*sec^{2})^{\frac{3}{2}}}*\frac{3}{2}*sec^{2}xdx \\\\\\ \int \frac{\frac{27}{8}*tg^{3}x}{(3^{2}*sec^{2})^{\frac{3}{2}}}*\frac{3}{2}*sec^{2}xdx \\\\\\ \int \frac{\frac{27}{8}*tg^{3}x}{27*sec^{3}x}*\frac{3}{2}*sec^{2}xdx \\\\\\ \int \frac{\frac{27}{8}*tg^{3}x}{27*secx}*\frac{3}{2}dx \\\\\\ \int \frac{\frac{27*tg^{3}x}{8}}{27*secx}*\frac{3}{2}dx \\\\ \int \frac{27*tg^{3}x}{8}*\frac{1}{27*secx}*\frac{3}{2}dx \\\\ \int \frac{3*tg^{3}x}{16*secx}dx\)
