I was working on the practice term tests in preparation for TT3 next week, and for Question 2a in both 2018STT2 and 2019STT2, we are asked to find the Wronskian for the given higherorder linear ODE. So, what I did to solve these questions was use the generalized Abel's Theorem that was proven as an exercise in the textbook in Section 4.1, Question 15d (pg 174 of Boyce diPrima). However, I couldn't remember seeing this result covered in lecture nor could I find any trace of it in my written notes. Thus, my question is: would it be okay to use the generalized Abel's Theorem to find the Wronskian for a higherorder linear ODE on the test, should we run into a question like that?

For higher order equations it is covered in MAT244LEC0201W6L2 (see modules). It is mandatory material.
