For z = 2-8 i, find the value of the expression exp(-5i22), and type its real part, imaginary part and principal argument in the boxes below. Your answers must be entered as exact values in Maple notation Do not use decimals. You may use trigonometric functions, for 123 example, 5*cos(6). You may use the exponential function of a real number only: for example, e should be typed as exp(123), but exp(123+456*1) will be marked wrong. You may type Pi (with a capital P) for the number . Your answers: (a) the real part of exp(-5iz2) is (b) the imaginary part of exp(-5iz2) is (c) the principal argument of exp(-5iz2) is P
