    You shall use the 2nd Fundamental Theorem of Calculus.

    If it was just INT(0,x)f(t)dt
    Then the derivative is f(x).

    Here it is INT(0,x^2)f(t)dt
    Use the chain rule.
    The inner function (the "u") is x^2
    The other function (the "f(u)") is INT(0,u)f(t)dt.

    Thus,
    2x*f(u)=2x*f(x^2)
