I'm new to mathematica, and I'm having problems with what would seem to be basic use of the DSolve function. When I type in the command
DSolve[y'[x] == x, y[x], x]
I get the result
{{y[x] -> x^2/2 + C[1]}}
which is what I should be getting. But then I try the same thing with an initial condition:
DSolve[{y''[x] == y[x], y[0] == 1, y'[0] == 1}, y[x], x]
And mathematica returns: 'No interpretations available'. This is especially puzzling because this equation, initial conditions, and syntax were taken directly from the Mathematica website, where it shows what should be the output:
{{y[x] -> e^x}}
Any help would be appreciated. I'm currently using Mathematica 8.0 if that matters. Thanks!
