Question: Define Amplitude and Polar form, thus determine the amplitude and polar form of the complex number
Amplitude is the angle between the real part and the imaginary part of a complex number, it is also known as principal argument () it can be in radian or degree.
tan-1) tan-1 () tan-1 1 45
Polar form is a mathematical representation that connects modulus/magnitude (ṝ) to the principal argument (Amplitude) in a complex number
Polar form r(Cos i Sin ) r cis
Polar form cis
