My ______ are gone.

[Aerith's Knight]

It wasn't me! I was too busy with my Differential Equations homework to steal the ______. (For the record I hate the method of Frobenius, it should not take more than a page of work to do one problem, they average about one and a half to two pages each and the assignment had 10 we had to do.) It doesn't help when the book decided to randomly use obscure notation for their solutions in the back, and the solutions manual itself solved the problems using completely different methods than what the examples in the book used for finding the recurrence functions in terms of n.

I once had to go through an entire math book of 300 pages to understand 10 lines of Linear predictive coding.

Trust me, this is not so strange. It's math.
