2) Heun's Method solves an y - F(t,y) with y(to)o with the iteration: y(t) y0 WI y where Hi with wi - a. Edit the given Euler's Method code 'eulerode to use Heun's Method. b. Test that your code works by comparing to 'ode45' for y , = t2+92 with y(0) by plotting solution on the intervals [0,0.85] [0,0.9 and [0,0.95 c. From part b. what is the limit ast1
