Let $u =\operatorname{sin}(x)$.

$k\operatorname{sin}(3x − 2) + C$
What is $k$?

Use $u$-substitution. Careful choosing a $u$.
Who has the higher power: $x^{−3}$ or $x^{−4}$?

Before integrating, rewrite the square root term in the integrand with a fractional exponent.

Recall that: $\int \ln(x)dx=x\ln(x)-x+C$

$9\int \frac{1}{9+x}dx$
