gradient & degree
The gradient of a line is the tangent of the angle of slope; that
is, the tangent of the angle between the line and the positive x axis.
The x axis has angle 0 with itself, so its gradient is tan(0) = 0.
The y axis makes an angle of 90 degrees with the x axis, and tan(90) = infinity, So the y axis has... | {"url":"http://www.mathisfunforum.com/viewtopic.php?pid=28905","timestamp":"2014-04-21T05:38:29Z","content_type":null,"content_length":"9736","record_id":"<urn:uuid:7e6ad32e-1b4f-4be8-9a5d-90ab849b94cb>","cc-path":"CC-MAIN-2014-15/segments/1397609539493.17/warc/CC-MAIN-20140416005219-00451-ip-10-147-4-33.ec2.internal.w... |

what happens if a second order det of hessian is negative?
Hessian matrix $H=\left(\begin{array}{cc}\alpha(\alpha-1)x^{\alpha-2}y^{\beta}&\alpha\beta x^{\alpha-1}y^{\beta-1}\\\alpha\beta x^{\alpha-1}\beta^{\beta-1}&\beta(\beta-1)x^{\alpha}y^{\beta-2}\end
