Since the original function of the definite integral of the triaxial ellipsoid surface area is not an elementary function, this calculator is specially designed to calculate the triaxial ellipsoid surface area.

Ellipsoid surface area formula

Standard formula: S=2 times the integral of 0 to a of 2*π*cd*dx =4/3ab*π
Approximate formula: ① S=πb/(100a)(17a+3b)^2
② S=4πb(sin45°(a-b)+b)
If high accuracy is not required, the two formulas ① and ② are basically satisfied.
If higher accuracy is required, the following formula can be used,
S=πb/(100a)(16.9a+3.1b)2((a-b)/a)6/arctg((a-b)/a)6
The above formulas are all approximate formulas, and the last one contains the circular severing formula, so the accuracy is higher.
