Consider the initial-value problem:
y' = cos(6t+6sin(y)), y(0) = 12
What can you say, and why, about each of the following?
(a) How many solutions, if any, there are to that initial-value problem.
(b) On what interval such solutions(s), if any, are defined
I've been working on this problem for hours now and am completely stumped. Any help would be appreciated thanks!
