Solve (D2-2D) Y=ex. Sinx by the method of variation of parameters.

I need an expert solution in MATLAB language for the question, and I need the solution to be using MATLAB and in the form of an image. I do not need any notes with the program, just an explanation at the end of the image. By the way, two questions. Q2. Write a MATLAB user-defined function, freefall(), that computes the velocity and the distance of a free fall object. The velocity and the distance of a free fall object can be written as: v = gt y = yo+gt² where yo is the initial position, t is the time travelled and g is the acceleration due to gravity (- 9.81 m/s2). Note that the initial position can only be a scalar value. Q7. Write a user-defined MATLAB Function for the following math function: ((xy-5)² z = if x, y > 0 elsewhere The inputs to the function are x and y, where the output is z. Write the function such that x and y can be vectors. I. II. Use the function to calculate z(3,4) and z(5, -7). Use the function to make a colored 3D plot of the function z for -5
