int_(0)^(2)(1)/(4+x-x^(2))dx

" (2) "int_(0)^(2)(2x)/(x^(2)-4)dx

Evaluate: int_(0)^(4)(1)/(x+sqrt(x))dx( ii) int_(0)^(1)(2x)/(5x^(2)+1)dx

int_(0)^(1)(1)/(x^(2)+4x+5)dx =

int_(0)^(1)(1)/(x + 4 - x^2)dx .

If int_(0)^(1) x e^(x^(2) ) dx=alpha int_(0)^(1) e^(x^(2)) dx , then

If I_(1)=int_(0)^(2)(x^(2))/([x^(2)-4x+4]+[x^(2)])dx and I_(2)=int_(0)^(2)(4)/([x^(2)-4x]+[x^(2)-4])dx then I_(1)-I_(2)=

If int_(0)^(1)f(x)dx=1, int_(0)^(1)x f(x)dx=a and int_(0)^(1)x^(2)f(x)dx=a^(2) , then : int_(0)^(1)(a-x)^(2)f(x)dx=

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
