D [17/2g1 integrate a fun C https //relate.cs Ilinois.edu/course cs101-sp18/flor session/3/839 /16/ Based on this idea, the following forrmula can be derived for approximating the integral where h is the width of the trapezoids, b n, and zi E 0, n, are he coordinates o the sides of the rapezo ds. The igure above visualizes the idea ofthe a trapezoidal rule. Implement this formula in a Python function trapczint f,a,b,n . You may need to check and see if b a, otherwise you may need to swap the variables. For instance, the result of trapezint math.sin,n,.math.pi,1 should be 0.9979 (with some numerical error). The result of trapezint ahs,-1,1,1) should be 1.. (This assignment is based on Langtangen, Exercise 3.11a.)
