Non linear 2nd order differential equation

Click For Summary
The discussion revolves around a request for step-by-step assistance in solving a second-order non-linear differential equation. Participants emphasize the importance of showing personal effort and providing a clear problem statement rather than relying solely on attachments. A template is suggested for structuring the inquiry, which includes sections for the homework statement, relevant equations, and the user's attempt at a solution. The conversation highlights the necessity of adhering to forum rules that require users to demonstrate their understanding before receiving help. Overall, the focus is on fostering independent problem-solving skills in mathematics.

please provide step by step method to solve this 2nd order non linear differential equation:
attached with this thread. take FUCOS(Ѡt) and FUsin(Ѡt) as zero.

Sorry, Chum, it's against the rules of PF to solve things for you. You've got to show some of your own work in order to get help.

Is this for HW?

Thread moved to HH/Calculus.

It looks like the PDF helps to define the problem, but you still need to show some effort on the math questions that you are asking. What approach do you think you should use?
 
Chumlee, here are the instructions you are missing and the template you need to fill out.

Use the template provided

• You must show your attempt at solving the problem
• Write the text of the problem here, not in an attachment or an image.

The Attempt at a Solution

 
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?
