<t>Quoteis my answer right?Think your answer is right in that the object will eventually come to rest in all directions, but the object will move along the x-direction because initally the net force along the x-axis is gravity only. The direction of fricitional force is opposite direction the instan...

oops Yes, then Legrangian is pretty ugly using corrdinate system x, y, z as defined below, but object would eventually come to rest in z direction.

<t>Soluation much easier to explain with picture (as most fresh physics questions are), but here goes. Change coordinates to parallel and perpendicular to the incline, call these x and y respectively. In the y direction you will have normal force pointing up and component of gravity pointing down wh...

could you explain the problem in a bit more detail? Also, seems Legrange multipliers could solve the problem analytically, or just use a contrained optimization algorithm to find the minimum surface area.

yes, that makes perfect sense. thnx !

<t>hello, Id like to compute the Delta of a Swaption. I've read some other posts on the subject here, but I guess I don't follow the exact calcualtion.Suppose I have a $100 notional 1Y5Y swaption, and I want to hedge it with the underlying fwd 1Y5Y swap. then, assuming Im usign black's model for pri...
