I'm given that an Euler equation (*) is of the form:
where a and b are constants. Then I'm told, let x=lnt, and calculate dy/dt and d2y/dt2 in terms of dy/dx and d2y/dx2.
But then I had problems with d2y/dt2.
This is what I got:
then subbing into (*) is good, except for d2y/dtdx term.
Any help would be greatly appreciated
