I have a problem
find the amplitude and plot the phase of the complex number
I have an exam tomorrow and this may come up not sure where to start, its basically the j at the start that is throwing me off, as i did not think it was possible to have a complex amplitude since it should be square root of the modulus.
thanks in advance for help
actually iv ended up with
that means part of the phase is not a multiple of j that cant be right?
(sorry dnt know how to use that equation tool)
or does that mean that the amplitude varies with t? with an amplitude of
