Hello,

For my homework I am supposed to get-

into the form of a Bessel equation using variable substitution. I am just not sure what substitution to use.
Thanks in advance.

Hello,

I apologize, I didn't read the rules properly beforehand. The question is part of a much longer, complex question, this is just the part I am stuck on and it is literally all the information I have to solve it. As for my efforts, well there are none right now. I have no idea where to even start on guessing what substitution to use.

Thanks
 

Thread 'Distance between a Clock's hands when the distance is increasing most rapidly'

Question: A clock's minute hand has length 4 and its hour hand has length 3. What is the distance between the tips at the moment when it is increasing most rapidly?(Putnam Exam Question) Answer: Making assumption that both the hands moves at constant angular velocities, the answer is ## \sqrt{7} .## But don't you think this assumption is somewhat doubtful and wrong?
