Complex numbers Flashcards
1
Q
If z = x + jy,
What is Re{z}?
What is Im{z}?
A
Re{z} = x
Im{z} = y
2
Q
How is a complex conjugate, Z*, obtained?
A
By changing the sign of the imaginary part. Conjugates are used in the division of complex numbers.
3
Q
What is the polar form of Z = Re{Z} + Im{Z}?
A
4
Q
How is the angle for polar form calculated?
A
tanØ = y/x
Ø = tan-1(y/x)
