You could substitute back in to your original equation and check.
Alternatively, feed it to the Wolf, which gives a slightly different solution.
Edit: For some reason that URL didn't work properly (though it did when I refreshed it - ho hum). But basically, your P.I is incorrect, the C.F is fine.
Edit2: Now it does appear to work. Wolfram not being consistent in its interpretation for some reason.

i got PI 2cosx again
You're right I made a stupid mistake it's 2cosx
Thanks
I also need help with this one: d^2y/dx^2 +3dy/dx = 9x^1 -1
Would the trial solution be qx^2 + px +r ?
Where p,q and r are to be determined
