Complex Functions: Phase Station

(Illustration)

Enter a complex function of position and time.  You should import the real and imaginary parts separately.

Try:  

• re = cos(2*pi*x/10-5*t)                                im = sin(2*pi*x/10-5*t)
• re = cos(2*pi*x/10)                                       im = 0
• re =  0                                                             im = cos(2*pi*x/10)  
• re = sin(pi*x/10)*cos(-2*pi*t)                     im = sin(pi*x/10)*sin(-2*pi*t)
• re = cos(3*x-3*t)+cos(4*x-4*t)                   im = sin(3*x-3*t)+sin(4*x-4*t)
