Derive and implement a Forward Differences Scheme to numerically solve the following and provide a plot of your solution between  = 0 and  = 5. 

Use a step size ℎ = 0.1, additional marks can be gained through analysis (e.g. errors, changes in step size, etc…)

dy a) dx = 4y, y(0) = 6 dy b) xcos(x) + 2, y(0) = 8 dx
