isi matrices in MatLab. Check the determinant first (solution to determinant in the Word file as well.Attach an m file with your work and comments and the Word file with your solutions You should NOT have any extra data besides solutions and graphs in your solutions/Word file. Have your name as part of both files: 2x+3Y = 1 3X + 4Y = 2 2. Same as problem 1 for following system of equations 3. Create 4 subplots using the subplot command On the first graph, plot angle in radians on the X axis from 0 to 2 in increments of 0.1 and sin(X) on the y axis For the second plot, same angle values on X axis and cos(X) on the y axis. On the third plot, same angle values on the x axis and log(angle) on the y axis On the last plot; same angle values on the x axis and tan (X) on the y axis. Put titles and label x and y axes for each plot. The entire curves should be visible (choose your X and Y axes values accordingly)
