`int x(1+x^(2))e^(x^(2))dx`

int(2x^(2)+1)e^(x^(2))dx

int(1-x^(-2))e^(x+x^(-1))dx=

int(1)/(x^(2)e^(a//x))dx=

int e^(x) ((1+ x^(2)))/((1+x)^(2))dx

Evaluate: int(2-x)/((1-x)^(2))e^(x)dx

If int _(0)^(1) e ^(-x ^(2)) dx =0, then int _(0)^(1) x ^(2)e ^(-x ^(2)) dx is equal to

show that (a) int_(0) ^(2pi) sin ^(3) x dx = 0 , (b) int_(-1)^(1) e^(-x^(2)) dx = 2 int_(0)^(1) e^(-x^(2)) dx

int(e^(x)(1-x)^(2))/((1+x)^(2))dx

int(x+1)^(2)e^(x)dx

int(e^(2x))/(1+e^(2x))dx=
