Assume that the repeating pattern of 4 squares followed by a circle and a triangle shown in Figure 9.51 continues to the right. Discuss whether the following reasoning is valid
Since there are 8 squares above the numbers 1-10, there will be 24 times as many squares above the numbers 1-240. So there will be 24 x 8 = 192 squares above 1-240. If the reasoning is not vatid, explain why not and find a different way to determine the number of squares above the numbers 1-240

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
