Just a quick query about calculating the area of an ellipse:
We've given the following parametric coordinates of an ellipse :
and and asked to find the area enclosed.
It's easy enough to find the following derivatives:
and
But then in the answers it's stated that:
The area of an ellipse is given by
Just wondering have they worked this out, or is this a common formula?
Thanks for the help
