Perimeter of Ellipse

[hazem]

My name is Hazem Albadry from Iraq born in 1956

Finally I discovered the exact formula of Perimeter of an Ellipse name (Hazem C-Ellipse) as following:

C = a * ((π-2)/45 * arcsine(b/a) + 4)

Where a is the major radius of ellipse
Where b is the minor radius of ellipse

When a=b then the formula will be C = 2aπ (As circle)
And when b=0 then the formula will be C = 4a (As lines)

I hope this help anyone who interested in Perimeter of an Ellipse.

Best regards.
