Taking an intro ODE class. Class just started and we are using a book, that to me, feels like en encrypted alien language. It is hard to read, but to much words and images, not enough layout. I'm more into theorem/proof style books. The book is too chatty. Well anyways.
It is giving problems trying to do my homework sets. For example.
Show that the implicit solution of 2x sin2 ydxx2 + 10 cos ydy = 0 is given by ln x2 + 10+csc y = c:
This is not explained clearly in the book. ( the directions).
Does this mean to just take the implicit derivative of ln x2 + 10+csc y = c and put into the form that contains the DE.
or does this mean to integrate 2x sin2 ydxx2 + 10 cos ydy = 0.
I am leaning on the implicit differentiation.I already worked out both ways. I am definitely going to get the library and get a book.
