The problems are in the uploaded file. 18) satisfies the differential equation
p(t) and q(t) are continuous
Wronskian of y1 and y2
The Attempt at a Solution
18) I don't really get this one
19) Solved most but at the end, where I got y2(t)=c*y1(t)
I got the value of c for when t=t* but here y2=0. Can I still use it here?
