Let (x) = 2x and consider the interval [1,2] . (a) Find a formula for Ry using the summation notation, and in terms of N. (b) Use Power Sum formulas to simplify the expression from part (a), and obtain an expression in terms of N without sigmas. (c) By evaluating the limit of the expression from part (b) as N , find the area between the graph of f and the x-axis for 1 x 2. Let (x) = 2x and consider the interval [1,2] .
