Calculus 1: U Substitution

Use U-Substitution to evaluate the following integral

$\displaystyle\int 4x(x^2 + 5)^{50} \ dx$

Evaluate the following integral

$\displaystyle\int\frac{\sin (\ln (x))}{x} \ dx$

Evaluate the following integral

$\displaystyle\int x^3 \sin (x^4 + 2) \ dx$

Evaluate the indefinite integral

$\displaystyle\int (x^4 + 2)^4 4x^3 \ dx$

Evaluate $\displaystyle\int (\ln{x})^4 \frac{2}{x} \ dx$

$\int{\frac{e^{arcsin(x)}}{\sqrt{1-x^2}}}dx$
