Min and Max distance to an ellipse in space

Calculus Level pending

An ellipse in the 3D Cartesian space is specified parametrically by

p ( t ) = p 0 + v 1 cos t + v 2 sin t \mathbf{p}(t) = \mathbf{p_0} + \mathbf{v_1} \cos t + \mathbf{v_2} \sin t

where p 0 = ( 2 , 1 , 5 ) , v 1 = ( 2 , 1 , 1 ) , v 2 = ( 2 , 2 , 2 ) \mathbf{p_0} = (2,1,5) , \mathbf{v_1} =(2,1,1), \mathbf{v_2} = (-2, 2, 2) . Find the minimum distance and the maximum distance from the point q = ( 3 , 2 , 9 ) \mathbf{q} = (-3, -2, 9) to the given ellipse p ( t ) \mathbf{p}(t) and enter the sum of these two values.


The answer is 14.912.
