A hyperboloid of one sheet has a saddle point (a point on a curved surface shaped like a saddle at which the curvatures in two mutually perpendicular planes are of opposite signs, just like a saddle is curved up in one direction and down in another).
If the "V" points to the correct position, the handle of the club will sit in between the thumb and the right index finger like a saddle at the top of the backswing.

After nearly two hours, we arrived at a saddle and a tight turn where the ground was soft and there was a big, knuckly tree root and then a step down, and Furman nearly fell again.
These two points correspond to a saddle point at ((0,0)) and a center point at (( -left[ 3u_{0}/2Aright] ^{2}, 0) ) in the phase portrait.
In this case, the potential well has one hump and a pit that correspond to a saddle point at (0, 0) and a center point at (( {h mathord{left/ {vphantom {h { alpha p^{2} )}}} right.
In this case, the potential well has one hump and a pit and this correspond to a saddle point at (0, 0) and a center point at (( {{[3h} mathord{left/ {vphantom {{[3h} {(2alpha p^{2} )}}} right. kern-0pt} {(2alpha p^{2} )}}]^{2} ), 0) in the phase portrait.
The complex anatomy of the Chopart joint, with a ball-and-socket articulation at the medial column of the foot and a saddle articulation at the lateral column, is an expedient biomechanical construction for accomplishing the complex tasks of the foot, namely optimally adapting to uneven surfaces upon first heel contact and forcefully pushing the foot off the ground at the end of the walk cycle.
He is now back in the saddle at Standard Chartered, a British bank that does much of its business in Asia, in a somewhat different but equally senior position he took up in mid-June, also in Singapore.
