Solve (1+2) = y +ln( y)e+!, y(0) = 2, h = 0.5, ispan= [0,2] dt a) By using Euler's method b) By using Heun's method c) By using Mid-Point method This task should be done on a paper and bring to the practical session. Clearly show all the calculations that you used. You may check your calculation by writing an M-file
