    Exclamation Parametric Equations

    Does anyone know how to find parametric equations for the curve segment:

    y=sqrt(x) from (1,1) to (16,4)?

    Thanks

    You can write lots of equations..

    x=t
    y=\sqrt{t}
    1 \leq t \leq 16

    x=t^2
    y=t
    1 \leq t \leq 4

    x=e^t
    y=e^{(\frac{t}{2})}
    0 \leq t \leq \ln 16

    x=\ln^2 t
    y=\ln t
    e \leq t \leq \ln e^4
