## Main Question or Discussion Point

I need help in understanding how to convert waves from instantaneous form to phasor form:

a wave expressed as E(z,t) = Eo * exp(-ax) * cos(wt - Bz) * ay

How do i convert this wave to phasor form and determine its direction of propogation, phase velocity and wavelength?

Thanks in advance for any advice.
