Chapter 5 - Section 5.2 - The Definite Integral - 5.2 Exercises - Page 388: 5

a) $6$ b) $4$ c) $2$

$Δx =\frac{10-0}{5} = 2$ a) $A = [ f(2) +f(4) +f(6) +f(8) + f(10)]Δx$ $A = [-1+0-2+2+4](2) = 6$ b) $A = [ f(0) +f(2) +f(4) +f(6) + f(8)]Δx$ $A = [3-1+0-2+2](2) = 4$ c) $A = [ f(1) +f(3) +f(5) +f(7) + f(9)]Δx$ $A = [0-1-1-0+3](2) = 2$
