Title: Different methods
Post by: Wei Cui on September 20, 2018, 04:31:45 PM
I find that there are different methods to solve for one differential question, even different profs have different methods (I guess they are the same in essence). Let's say when we solve the problems on our test or quiz, can we use a method which may differ from the one in the sample solution? Is there any formal format we should follow or as long as we solve the question, then we are fine?

Some equations admit different methods, and they are not always "the same in the essence". If in the problem the method is not specified, you can use any. If it is specified, there could be a deduction if you do not follow

During the exam or the quiz, do we have any hints for the method to solve questions? Like setting $Y = uy$
