To get it in this form we had to assume M = 2*M1/2+1. so . There were some other step to get it into the equation form but this is where it originated from.
Sorry about the late response. It is M1/2 as a subscript, I attached a picture. I am going to the math department for some guidance since I can't seem to figure this one out. Any help would be appreciated,
Homework Statement
I have to simplify this beam form (equation 1) which simplifies to equation 2 and then finally to equation 3.
Homework Equations
equation 1: e^-ix((1-e^y)/(1-e^z)) where x = Beta*M_(1/2), y = beta*M, z= Beta
equation 2: sin(M*Beta/2)/(sin(Beta/2))
equation 3...
