Intrinsic to Cartesian Help

Does anybody know any website where they explain this process I've searched high and low and found nothing at all

an arc length? perhaps you mean a radius in which case you're talking polar coordinates, which I could explain roughly.

I've never heard of a coordinate system which defines in terms of an angle and arc length :|

Nope I know polar coordinates, I do mean arc length. They're also reffered to as natural coordinates

here,

I love you .

Nah, really, you've saved my skin, thanks so much .

love me? alllllrightey then,anyway if u need any more help.....
all u have to do is remember what dx/ds and dy/ds is equal to,then play around with the expression to convert frm intrinsic to cartesian.
By the way were are u gettin these qu from

Wanna get married?

We got a truckload of papers to do, this was the P5 Mock, and there's just that locus one left now, I managed to work my way through the rest (with some help). I've scanned the paper in, along with a heap of others I have (something like thirty) and am planning to upload them to the web somewhere
