    Point of intersection

    What is the point of intersection between the curves y=secx and y=4?
    I need it in order to find the area of the region bounded by the two curves.

    Thanks.

    The y-values must be equal:

    \sec^2(x)=4

    |\sec(x)|=2

    \left|\dfrac1{\cos(x)}\right|=2

    \cos(x) = -\dfrac12~\vee~\cos(x)=\dfrac12

    Can you take it from here?
