: Making The Substitution Y U 1 Gmu Show That U Y 1 Gmy O Gmu 2 Therefore Rewrite The Lensing Equation 1 1 Do D 1 (19.18 KiB) Viewed 23 times

Making the substitution y= u(1 - GMu), show that u = y(1+GMy) + O(GMu)2 Therefore, rewrite the lensing equation 1 1 do dr + 1 = (1-2 26M)] 2 As do dy Il 1+2GMy + O(GMy 6-2 - y2
