I'm learning very basic diffeqs in another math class, and the type of problems were doing are first order separable differential equations, very basic stuff.
I'm trying to use Mathematica/Wolfram Alpha to check my answers, but everytime, wolfram will output the incorrect answer and I will always have the correct answer and I can't figure out why
I calculated y to be:
When simplified, this matches the back of my book. Great. When I type the same problem for Wolfram Alpha to solve, I get back this:
Which is completely wrong. Could this be a bug in the CAS?
You continue to make that mistake by letting "the constant = 4.5 in both equations."
In my previous reply I showed you why the answers were equivalent (equivalent does not mean equal, by the way).
Calculate the arbitrary constant in each solution for the initial condition y = 1, x = 0 and you will discover that each gives the same rule for y (provided you do this correctly, of course).
