I'm relatively new to Mathematica, and I'm having trouble with a simple DE.
This is from Zimmerman & Olness, "Mathematica for Physics". Here's the
equation:
eq1 = y''[t] + w^2 y[t] == 0
initial = {y[0] == y0, y'[0] == v0}
eq3 = DSolve[{eq1, initial}, y[t], t]
When this executes, I get the error message bvnul: For some branches of the
general solution, the given boundary conditions lead to an empty solution.
Now, if I change v0 to a number, everything works fine. I've tried making
v0 real and positive, but with no luck.
Any help is appreciated.
