EXERCISE 1.3
8
1) Find the modulus and amplitude for each of
the following complex numbers.
1) 7-51 in) √3+ √21 m) -8 - 151
iv)-3(1-1) )-4-41 vi) 31
vii) 3 viii) 1 + i iv) 1 + i 13
x) (1+21) (1-1)​

Answer 1

amplitude of last example :

tan A = b/a

= 7/1

tan A = 7

A = 7

tan

= tan inverse 7

consider A = theata
