Question

In polar form z = r(cos θ + i sin θ), r is called the ___ and θ is the ___:

Accepted Answer

B. Modulus; argument

r = |z| is the modulus (magnitude).
θ is the argument (angle from positive real axis).
r and θ together specify z in polar form.

Answer

Conjugate; phase

Answer

Argument; modulus

Answer

Real part; imaginary part
