I've got a homework question I reallly need answered quick, I have the question: Evaluate the Integral of (4x^2-9)^1/2 I think a trig substitution could be in order here...but not sure. Thanks in advance for the help!

Thanks in advance for the help! Actually the substitution $\displaystyle x = \frac{3}{2}sec(x)$ would be more useful. -Dan
