| Hello:
|
| Is there a way in Mathematica to check whether 
an algebraic expression is
| positive or negative, and a way to specify 
conditions on the variables in
| the expression? For example, is there a way to 
check whether x^2 is positive
| for any real x? I want to check this for a 
complicated
| expression...basically the sign of the second 
derivative of a function.
|
| Thank you very much for your help.
|
| Bharat.
