    inverse function challenge

    Can someone show me the way?

    I need to find the inverse of f(x) = 9 + (X squared) + tan(Pi times X/2)

    Perhaps there are tools on this website for writing the equation. I hope you can understand.

    f(x)= 9+ x^2+ tan(\frac{\pi}{2} x)
    Click on that to see the code. There is also a thread titled "Latex Help" under "Math Resources".

    What do you mean by "find the inverse"? That is not a one-to-one function and so has no inverse. Even if you were to restict the domain to, say 0 to \pi/2, I don't believe it has an inverse in terms of elementary functions.
