Using MATLAB, express each of the following complex numbers in Cartesian form, i.e., s = a + jb, where a = Re(s) and b = Im(s). Plot part (a) in the complex plane: a. je^{j11pi/4} b. (1-j)^{10}. 2. Add the function p=3sin(x^2) + 2cos(y^3) and q=3cos(xy) + 2y^2 for x in the range 0 to 5. Y = 0.05x + 2.01 in all cases. Use increments of 0.01. Plot all three functions. 3. Plot the following: a. z = 3+j4.
