why is psi = cos (k r - w t) + i sin ( k r - w t) = e^ [ i ( k r - w t)]?(adsbygoogle = window.adsbygoogle || []).push({});

my question precisely is why not:

1. psi = sin (k r - w t) + i cos ( k r - w t) ?

2. psi = sin (k r - w t) + i sin ( k r - w t) ?

3. psi = cos (k r - w t) + i cos ( k r - w t) ?

why not any of these three? is there a reason it is only the first form?

this means that there always has to be reflection between the real and imaginary parts of the wave function and i don't know why??

Also,

when solving the Schrodinger's equation we assume that

PSI (r,t) = psi (r) X phi (t)

Why this form in particular not another form including addition or subtraction wouldn't this be possible and why???

thanks
