Sum and constant-multiple rules: State the sum and constant-multiple rules for (a) derivatives and (b) limits.
Use integration formulas to solve each integral in Exercises 21–62. You may have to use algebra, educated guess and-check, and/or recognize an integrand as the result of a product, quotient, or chain rule calculation. Check each of your answers by differentiating .
Consider the region between f and g on [0, 4] as in the
graph next at the left. (a) Draw the rectangles of the left-
sum approximation for the area of this region, with n = 8.
Then (b) express the area of the region with definite
integrals that do not involve absolute values.

Without calculating any sums or definite integrals, determine the values of the described quantities. (Hint: Sketch graphs first.)
(a) The signed area between the graph of f(x) = cos x and the x-axis on [−π, π].
(b) The average value of f(x) = cos x on [0, 2Ï€].
(c) The area of the region between the graphs of f(x) =
