complex number

if I have the absolute and the angle of a complex number, How i get the number in form of real and imaginary parts ?

Answer 1

[Grzegorz Knor]

Z = R.*exp(1i*theta)

where:

R = abs(Z)% magnitude
theta = angle(Z) % angle

Answer 2

Hello !!

Lets say r is the amplitude θ is the angle .

Thus the complex number formed shall be = rcosθ+rsinθi .

Real Part = r*cosθ ,

Imaginary Part = r*sinθ

Here i = iota ( complex number imaginary part operator)

I hope it will help future readers
