SUMMARY
The integral of the absolute value function ∫0-->x |t|dt can be evaluated as 1/2*x^2 for x ≥ 0 and 1/2*(-x)^2 for x ≤ 0. The correct expression for the integral across both domains is 1/2*x|x|, as confirmed by the textbook answer. Participants in the discussion clarified the evaluation process and addressed common misconceptions regarding the negative sign in the integral for negative values of x.
