Reduction formula integration method help

Click For Summary
The discussion centers on the reduction formula as a method for solving integration problems, highlighting a lack of comprehensive resources on the topic. The main inquiry is whether there is a general method to derive the reduction formula for any function of the form u^n. Participants suggest that the approach may depend on the specific function being integrated. Integration by parts is mentioned as a well-known technique for deriving reduction formulas. Overall, the conversation emphasizes the need for clearer guidance on creating reduction formulas for various functions.

Homework Statement


Well, I've been doing a lot of research about the reduction formula as a method for resolving integration problems. However, not much information on the topic is to be found about the topic. The only things i get to find are examples with the formulas already given, which is cool, but still not what i need.

The Question is ¿is there a general method to find the reduction formula for any given u^n function?
Thanks.

It depends on the function it self.
Personally, I think integration by parts is the famous way of finding the reduction formulas.
 
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?
