Hi Ramakrishnan,
We're almost there, but you neglected one of the comments I made about
your previous patch.

I repeat: In the equation above, -x^n parses as -(x^n), but it should be
(-x)^n. Same problem with (-1^n). Exponentiation has higher precedence
than negation.
The equation above should be: (-x)^n = (-1)^n * x^n
Feel free to add more parentheses if you like, but the ones I have
included are essential and must not be removed.
Everything else looks good to me.
Thanks,
Mark
