Question: Let (x) = 1/x, x 1 = 1/2, x 2 = 1, x 3 = 3/2, x 4 = 2, and x = 1/2. (a)

Let ƒ(x) = 1/x, x₁ = 1/2, x₂ = 1, x₃ = 3/2, x₄ = 2, and
Δx = 1/2.

(a) Find 4 +(x;).. i=1 (b) The sum in part (a) approximates a definite integral using rectangles. The height of each rectangle is given by the value of the function at the left endpoint. Write the definite integral that the sum approximates.
