Evaluate the deep reckon progressive by applying the deep reckon manipulating rules. Write the end in the polar shape. z = (5-j6) – (2-j8)/(-3+j4)(5-j) + (4-j6) Let z_1, z_2, z_3 be three deep reckons whose maximums and bearings are r_1, r_2, r_3 and theta_1, theta_2, theta_3 respectively. Obtain expressions of maximum and bearing of the subjoined deep reckons in provisions of r_1, r_2, r_3 and theta_1, theta_2, theta_3.
