1. Let x is be an array that takes on the values x 1, 1.2, 1.4...... 5. Use Matlab to compute the array y that results from the function y =7 sin (4x). Use Matlab to determine how many elements are in the array y and the value of the third element in the array y. 2. Use matlab to determine how many elements are in the array sin (-pi/2): 0.05: cos (0). Use matlab to determine the 10th element. Complex numbers: 3. Let x-7-5i and y = 4 +3i. Use Matlab to compute a) x+y, b) x *y and c) x/y. 4. Enter and explain the result of each of the following statements. a) x=-3-j*4, b) y = complex (-3,-4). c) x_r=real(x) d) x_i=imag(x), e) z= conj(x) 1.
