" (a) "int_(-1)^(2)2^(x)dx

(1) int_(1)^(2)(2x^(3))dx

int_(1)^(2)|2x-1|dx

int_(1)^(2)[2x]dx

If I_(1)=int_(0)^(1) 2^(x^(2)) dx, I_(2)=int_(0)^(1) 2^(x^(3)) dx, I_(3)=int_(1)^(2) 2^(x^(2))dx and I_(4)=int_(1)^(2) 2^(x^(2))dx then

If I_(1)=int_(0)^(1) 2^(x^(2)) dx, I_(2)=int_(0)^(1) 2^(x^(3)) dx, I_(3)=int_(1)^(2) 2^(x^(2))dx and I_(4)=int_(1)^(2) 2^(x^(3))dx then

int(1)/(2)(3-2x)dx

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

Prove that int_(-2)^(2)|1-x^(2)|dx=4
