    Intersect of two curves

    I really should know better but because a) I have no textbook and b) the internet was unyielding to my searches I have come to ask my question here which I really should know but it evades me.

    How do I find the points of intersect of the curves x^3 and x^{-3}?

    P.S I don't have a clue where to start either

    Any help is greatly appreciated

    x^3=\frac{1}{x^3}

    x^3x^3=\frac{x^3}{x^3}=1

    x^{3+3}=x^6=1

    x=\pm1

    Thankyou

    I feel EXTREMELY dumb but then again I have been doing a lot of revision for more important subjects than maths and my brain is a sludge atm. Not going to have fun in the test tomorrow

    Don't feel that way, Beard,
    mental tiredness causes that,
    happens to me at 2am every night.
