Equation of the Week #7: The Complex Argument
|
|
the complex argument is a function which is comonly used in functions such as complex exponentiation; it is a function which takes a Complex number and returns a real number to put it into easy to understand terms:
ARG(X + i * Y) = ARCTAN(Y / X)
Or to put it in terms of qb64 code:
ARG(X + i * Y) = ATN(Y / X)

tan is sin/cos so is [exp(ix)+exp(-ix)]divided by i*{exp(ix)+exp(-ix)}
Now exp(ix) has 2 arguments i and x
So I do not understand why you talk of ARG(x+iy)
