1. ## Parametric Equations

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

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

Thanks

2. You can write lots of equations..

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

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

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

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