Homework Statement
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
Homework Equations
The S is the integration sign
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?
