Given that the intrinsic equation of a curve is s = a sec ^ { 3 } \ psi-a where a is a non zero constant, I have to show that y = atan ^ 3 \ psi.

In 1972 H . Hasimoto used Da Rios'" intrinsic equations " ( later re-discovered independently by R . Betchov ) to show how the motion of a vortex filament under LIA could be related to the non-linear Schr�dinger equation.

The Whewell equation and other types of so-called intrinsic equations have applications in the solution of certain physical problems, but for computer graphics it's apparently more practical to use compound polynomial approximations as in B�zier splines .-- talk ) 19 : 55, 31 August 2015 ( UTC)
