I have solved the question i just need help doing matlab code for part a

Problem l 9: Give expressions for yC, for a sinusoidal wave traveling along a string in the negativex-direction, given thatymax 40 cm, -30 cm,f-10 Hz, and (b yCx,00 0 at x 3.75 cm. Use the solution for part 20a) and plot yGr 0,)(i.e. sweep t to generate to generate the plot Submit your handwritten solution, MATLAB code, and apha Hints: You need to plot the equation of a wave with t as the independent variable. Refer to the MATLAB tutorial on how to enter variables and plot a sine wave. For this problem, your equations are in tems of cos. Define t as varying from 0 to 2 T where Tis the period of wave. Generate 200 data points for T the cosine Don't forget to include the phase an in your equation. In MATLAB, the tems inside the parenthesis for sin or cos should be in radians. If your handwritten answer is in degrees, you can convert from degrees to radians using the function deg2rad Grefer tutorial section T) If there are two solutions for the phase angle, you can plot for either of them and indicate which solution you have used
