    Red face integral

    I solved this integral, however, I need some help evaluating it with the upper and lower bounds. My answer seems a bit odd.

    Integral 3/(sqroot1-x^2)dx

    I got 3inverse sinx from -1 to 1 but when I plug the values in i'm not sure how to report the answer.

    What's the trouble? \sin^{-1} (1) = \frac{\pi}{2} and \sin^{-1} (-1) = - \frac{\pi}{2} ....

    It seems there was a mistake on my solutions manual that led me to believe I had the wrong answer. Thank you!
