Matlab project 1 1 Plot the directional field of the differential equation in the rectangular region [0, 5] [-2, 2] on the (t,y)-plane. 2 Using Euler approximation to solve the differential equation under the initial condition (0)1.5 and add the graph of the solution curve to the plot of the directional field. 3 Compute and display y(3.5), the value of the solution at t 3.5 You should submit the following items 1 Matlab codes for your program and function 2 Printout of matlab session including the value y(3.5). 3 Plot containing both the directional field and solution curve. See the sample for more details. Note that the matlab codes for et and Int are respectively exp(t) and log(t)
