    If you graph a sine wave and an x^2 it seems that 0 and .88 are the (x value) points where the two intersect. I would believe that .88 is in radians mabye? I sure hope this is college level trig and not high school:) Sure would be nice to know the answer.

    I don't think that there's a closed form in cartesian space... there might be one if you convert to polar.

    Since this a calculus course, you're probably supposed to use Newton's method... if you graph x^2-sin(x) and tell your calculator to find the roots, that's what it'll use (or Newton-Ralphson, but whatever).

    I forgot about this darn thing....

    Sin(X)=Opposite/Hypot=Y/Rt(X^2+Y^2)=X^2

    solve for Y
