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

int_(-1)^(0) (dx)/( x^(2) + 2x+ 2) is equal to

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

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

int_0^1 (x/(x+1))dx

int_(0)^(1) x dx

Let I_(1) = int_(0)^(pi//4)1/((1+tanx)^(2))dx , I_(2) = int_(0)^(1)(dx)/((1+x)^(2)(1+x^(2))) Then find the value of (I_(1))/(I_(2)) .

The value of ("^n C_0)/n + ("^nC_1)/(n+1) + ("^nC_2)/(n+2) +....+ ("^nC_ n)/(2n) is equal to a. int_0^1x^(n-1)(1-x)^n dx b. int_1^2x^n(x-1)^(n-1)dx c. int_1^2x^(n-1)(1+x)^n dx d. int_0^1(1-x)^(n-1)dx

Evaluate: int_(0)^1(dx)/(1+x^2)

int_(0)^(1)(dx)/(1+x)
