1. The problem statement, all variables and given/known data a) S(4 is higher limit, 0 is lower limit) (x^4 - x^2 + 1)dx b) S(pi is higher limit, -pi is lower limit) (cosx + sinx)dx 2. Relevant equations The S is the integration sign 3. The attempt at a solution a) = ((x^5)/5)-((x^3)/3)+x I(4 high, 0 low) = (((4^5)/5)-((4^3)/3)+4)-(0) Is this the final solution or is there another step i don't know about? b) = (sinx + -cosx) dx I(pi high, -pi low) = (sin(pi)-cos(pi))-(sin(-pi)-cos(-pi)) Is this the final solution?
