Let expr be an expression which depends on a and b.
How can I check the sign of expr (e.g. positive) when
a and b satisfy some inequality constraints?
Example: f=(-9 - 23*c4 - 19*c4^2 - 5*c4^3 + 9*nu + 21*c4*nu + 15*c4^2*nu)
Check the sign of f when -1 < c4 < Infinity and 0<= nu <= 0.5
Thanks in advance,
