Hi to all.
I have a differential equation with a strange out put when using DSolve:
1) When I put
DSolve[y'[x] == Tan[x + y[x]] + 1, y[x], x]
Mathematica can solve it!
2) When I put
DSolve[y'[x] == Tan[x + y[x]] - 1, y[x], x]
Mathematica is able to solve it also!
3) But the strange out put is when you put
DSolve[y'[x] == Tan[x + y[x]], y[x], x]
the no any out put!!! just {} !!! the same as in the explicit form!
Although the Maple could solve it, but I like the Mathematica and want to stay with it!
Does any body know why the empty answer!??
Mathematica Version - 6 (Linux Ubuntu)
