(choose chapter or problem)

Evaluate the integrals using the indicated substitutions.

(a) $\int \frac{d x}{x \sqrt{9 x^{2}-1}} ; u=3 x$

(b) $\int \frac{d x}{\sqrt{x}(1+x)} ; u=\sqrt{x}$

Equation Transcription:

∫ $\frac{dx}{x\sqrt{9{x}^{2}-1}};u=3x$

∫ $\frac{dx}{\sqrt{x}(1+x)};u=\sqrt{x}$

Text Transcription:

integral dx/x sqrt 9x^2 -1 ;u=3x

integral dx/x sqrt 1+x ;u=sqrt x
