a.Draw a design made of small circles ( or another shape) so that the total number of circles in the design is
And so that you can tell this expression stands for the correct number of circles or evaluating the expressions . Explain briefly.
b. Write another expressions for the total number of circles in your design in part (a) Explain briefly ( your expression should . Not consists of a single number.) Discuss connections to material you have studied previously ( see chapter 4

Hint: Find the limits on r and s by sketching the area of integration in the (x, y) plane along with the r and s axes, and then show that the same area can be covered by s from 0 to r and r from 0 to 1.arrow_forward
