Make the change of variable and rewrite the de in terms of and . Then put and you should find that and satisfy the Bessel equation of order .
thanks for the reply
just one more question.
how do you know which variable to use??
for instance, how do you choose the 'change of variable'?
By comparing the Bessel equation with that given, and more directly looking at the form of the solution that you are to demonstrate. (in fact the suggested change of variables comes directly from the suggested solution)
