The trail starts at the McCray Road parking area and runs for about 1 mile to a connection with a city of Cloverdale trail. The city trail runs 0.3 miles to the downtown area.
Intermediate Value Theorem. The Intermediate Value Theorem says that if a function is continuous and it's positive somewhere and negative somewhere else, then the function has to equal zero at some point between those two values. The important part of this theorem is to note that f(x) must be continuous.
A simple criterion for checking if a given stationary point of a real-valued function F (x, y) of two real variables is a saddle point is to compute the function's Hessian matrix at that point: if the Hessian is indefinite, then that point is a saddle point.
