converting phasor form to real time form

convert to phasor form

I need help converting the following two phasor eqns into real time forms. Having problems with the imaginary (j). Side note, eqns below are related to electric and magnetic fields.

Em = constant
j = imaginary
B = beta
z = distance z


phasor form: k*sin(pheta)/(2*pi*epsilon)*e^(-j*B*r)*j*w/(c^2*r)

convert into real time form
k = constant
pheta = angle
epsilon = constant
B = beta
r = distance r
w = omega
c = constant

phasor form

ur equatin aint clear enough, i cant understand it
if u wanna convert a phasor form into real time form u multiply it with e^jwt
w= omega
t = time

and then using euler identity e^x = cos(x)+j*sin(x)
and take the real part of it (without j factor)
u get the real time from from phasor form

may this helps

converting phasor form to j

beside that you can try wiht derive and get the solution.

What's pheta cause i never heard of this greek symbol?
Masadi is correct that your equation is not clear! Another thing:

e^(-j*B*r)*j*w = e^(B*r*w) = not imaginary!
