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

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

Evaluate as the limit of sums: int_(1)^(2) (x^(2)-1)dx

Evaluate "int(1)/(a^(2)-x^(2))dx

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

Evaluate: int_1^2x^2dx

"int sqrt(1^(2)+x^(2))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, I_(4) = int_1^(2) 2^(x^(3)) dx then,

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