Textbook Question

Chapter 6.2, Problem 74E

Geometric probability Suppose a dartboard occupies the square {(x, y):0 ≤ |x| ≤ 1, 0 ≤ |y| ≤ 1}. A dart is thrown randomly at the board many times (meaning it is equally likely to land at any point in the square). What fraction of the dart throws land closer to the edge of the board than the center? Equivalently, what is the probability that the dart lands closer to the edge of the board than the center? Proceed as follows.

a. Argue that by symmetry, it is necessary to consider only one quarter of the board, say the region R: {(x, y): |x| ≤ y ≤ 1}.
b. Find the curve C in this region that is equidistant from the center of the board and the top edge of the board (see figure).
c. The probability that the dart lands closer to the edge of the board than the center is the ratio of the area of the region R₁ above C to the area of the entire region R. Compute this probability.

This question builds on an earlier problem. The randomized numbers may have changed, but have your work for the previous problem available to help with this one. A 4-centimeter rod is attached at one end to a point A rotating counterclockwise on a wheel of radius 2 cm. The other end B is free to move back and forth along a horizontal bar that goes through the center of the wheel. At time t=0 the rod is situated as in the diagram at the left below. The wheel rotates counterclockwise at 1.5 rev/sec. At some point, the rod will be tangent to the circle as shown in the third picture. B A B at some instant, the piston will be tangent to the circle (a) Express the x and y coordinates of point A as functions of t: x= 2 cos(3πt) and y= 2 sin(3πt) (b) Write a formula for the slope of the tangent line to the circle at the point A at time t seconds: -cot (3πt) (c) Express the x-coordinate of the right end of the rod at point B as a function of t: 2 cos(3πt) +41/1 (d) Express the slope of the rod…
