Approximate 5 points The value of equals the circumference or a circle with radius 1/2. Suppose we approximate the circumference by a polygon through n + 1 points on the circle. The length n +1 points ( ) along a circle with radius 1/2 according to the formulae of this polygon can be found using the pathlength function from the previous exercise. Compute Isin(22) 2 i=0, . . . , n. Write a function circle pts( n ) which accepts a number of sides n and returns a pair of list s (as a tuple ) containing the x and y coordinates of the approximating polygon You will need to include your working pathlength function from the previous exercise. write a function approx-pi ( n ) for approximating by the path length L re Your answer should include three functions: pathlength, circle pts, a (This assignment is based on Langtangen, Exercise 3.18.) nd approx pi Answer Approximate 5 points The value of equals the circumference or a circle with radius 1/2.
