Hi there!

Here is the solution in two file formats as usual.

I'm sorry it took me a while, but I wanted to show you two different methods how to approach this kind of problem (who know's in a test it might come handy).

First Method: Wronskian

Write the equation as:

The two solutions must satisfy:

Multiplying equation (2) by y1 and subtracting equation (1) multiplied by y2 we obtain:

Using the Wronskian's definition:

We see that:

So:

This ...
