1. The problem statement, all variables and given/known data The question is pretty basic, but for some reason I cant find a way to do it. I just need to find out what Eo is. I am given nTo= Eo-(2/7)sin(Eo) n=1 rad/tu To = 2.146 tu 2.146 rad = Eo - (2/7)sin(Eo) 2. Relevant equations 3. The attempt at a solution I tried to factor out Eo. so 2.146 = Eo(1-(2/7)sin(theta). but obviously that doesnt work.
