Dear All,
(This is a math problem. Solving an equation)
I am trying to extract the coefficients in eq2 ( Derivative[1][[Psi]][[Xi]]/[Psi][[Xi]]) and then set them equal to zero.
But it's not possible. Can you help me?
You can set the denominator to 1:
1
eq2 /. \[Psi][\[Xi]] :> 1 CoefficientList[%, \[Psi]'[\[Xi]]]
