Critical Point (mathematics)
In calculus, a critical point of a function of a real variable is any value in the domain where either the function is not differentiable or its derivative is 0. The value of the function at a critical point is a critical value of the function. These definitions admit generalizations to functions of several variables, differentiable maps between Rm and Rn, and differentiable maps between differentiable manifolds.

Famous quotes containing the words critical and/or point:
“Good critical writing is measured by the perception and evaluation of the subject; bad critical writing by the necessity of maintaining the professional standing of the critic.”
—Raymond Chandler (1888–1959)
“The point is that nationalism, even in its latest madhouse frenzies under Mussolini and Hitler, is still, like advertising, an arm of big business. Nations as we know them today, were the invention of business and it is natural that business should still consider itself slightly above patriotism and that the strongest international should still be the international of profits.”
—John Dos Passos (1896–1970)
