" Let "I=int_(0)^(1)(2+3x+4x^(2))/(2sqrt(1+x+x^(2)))dx." Find the value of "I^(2)

Let 1=int_(0)^(1)(2+3x+4x^(2))/(2sqrt(1+x+x^(2)))dx. Find the value of I^(2).

I=int_(0)^(2)x sqrt(4-x^(2))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)) .

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)) .

Let I=int_(0)^(1)(x^(3)cos3x)/(2+x^(2))dx, then

" (i) "int_(0)^(3)(dx)/((x+2)sqrt(1+x))

I=int_(0)^(2)(3x^(2)-3x+1)cos(x^(3)-3x^(2)+4x-2)dx

I_(1)=int_(1)^(2)sqrt(sin(3x-x^(2)-2))dx and I_(2)=int_(1)^(3)sqrt(sin((4x-x^(2)-3)/(4)))dx then the value of 2I_(1)-I_(2) is

Let I_1=int_0^1e^(x^2)dx and I_2=int_0^(1)2x^(2)e^(x^2)dx then the value of I_1 +I_2 is equal to

Let I_1=int_0^1e^(x^2)dx and I_2=int_0^(12)2^(x^2)e^(x^2)dx then the value of I_1 +I_2 is equal to
