Ok so I've got this question that I dunno how to do the first part.
An ellipse has parametric equations
Show that the length of its circumference is given by
(thats the part i dont understand)
The integral cannot be evaluated in terms of elementary functions. USe the trapezium rule with interval-halving to evaluate it to 6dp. (<- I can do this part)
I've never done anything like the first part before :s
I found a formula
not sure if it's any good for this
all i done so far is find
Circumference of parametric ellipse? Watch
