Computing a 3x3 determinant and Wronskian of 3 functions

Differential Equations--how do we find a 3x3 determinant (formula) and a sample Wronskian of 3 functions. Recall if 3 functions have a nonzero Wronskian on some interval, they are linearly independent on that interval

Especially solutions of differential equations via power series technique.

Good job.

Thank you very much it was quite easy to understand, one question: is there any restriction to where the colum to expand can be placed? for example using a11 a21 and a31 or in the other example use the colum 1 0 0 to make the process much faster

Where did you get e^12x from?
