1. ## Parametric Surface Area

There might be a 2nd way to do this. Take the square root of dx/dt and dx/dy and then multiply by the x (the x where you have to plugin an equation) and then do the power rule to integrate.

2. ## Re: Parametric Surface Area

Hey Jason76.

If you are finding the surface area then you will be looking at two dimensional analogue of arc-lengths where you add up strips of arc-lengths to get surface area in which the same way that a normal integral adds up strips whose width tends to zero.

I should probably ask what material you are being taught though because chances are that your professor wants you to use specific results rather than deriving your own.
