I know the $\surd$ sign refers to the positive square root. Does the exponent 1/2 mean the positive square root too by convention?
I ask because I'm converting from parametric to cartesian here...
$x=t^2$ and $y=t^3$
So $t=\pm \sqrt{x}$
Then $y=\pm x^{3/2}$
Yet the given answer is $y=x^{3/2}$ in the textbook. Can someone clarify please?
Thanks, Rob
