Question

please just answer the last 2 bullet points

P1) The velocity u of a racing car can be modelled by the differential equation shown below I du ー-4に! If the initial velocity of the car (at 0s) is 1 m/s, determine the velocity after 0.75 s using: (a) Integral calculus (b) Euler's method with a steg size of 0.25 s (c) Ralston's method with a step size of 0.25 s Plot all velocities (at all steps) for all the above methods on the same graph (using MATLAB/Excel). For each numerical method, calculate the true percentage relative errors at all steps What do you need to calculate the percentage approximate relative errors for each method? No need to calculate the percentage approximate relative errors.
