Hwe-1. Suppose that u= 1 and v-3, evaluate the following expressions using MATLAB. (4) Vu - 3v 3v (5)(u + cos(v)) 2v-2 (1) : (3)- (6) sin (0.7) v-u %input code here u = 1; V 3D 3; 4*u/(3*v) 4*pi/3*v^2 2*v^(-2)/(u+v)^2 srt(u-3*v)/(3*v) eq5 = (u+cos (v)^2)/(v-u) ep6 = pi/3*sin(e.7*pi) eq1 eq2 eq3 eq4 !! Hwe-2. Click "file" -> "new" -> "M-file"on the desktop menu to create a new M-file, type the following statements into the file, and save with the name try1.m. x = 0:0.1:10.0; y = 2*exp(-0.2*x); plot(x, y); Then execute the program by typing the M-file name try1.m in the command window. What result will you get? %input code here
