(choose chapter or problem)

In the following exercises, verify each identity using differentiation. Then, using the indicated u-substitution, identify f such that the integral takes the form \(\int f(u) d u\).

\(\int \frac{x}{\sqrt{4 x^{2}+9}} d x=\frac{1}{4} \sqrt{4 x^{2}+9}+C\) ; \(u=4 x^{2}+9\)

Text Transcription:

int f(u) du

int x/sqrt 4x^2+9 dx=1/4 sqrt 4x^2+9+C

u=4x^2+9
