MonotonicityDiscuss the monotonicity of f(x) = 30x^9 + 2x^8 + 300x^7  (17/2)x^6  x^5 + 3x^4 +973x^3  200x^2 + x + 1 . El que pega primero pega dos veces. #2 20051024 17:53:41
Re: MonotonicityYep, that "x" sure is monotonous "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #3 20051025 00:18:13
Re: MonotonicityWhat about something like y = x³? That's mostly always increasing, but it also has a flat bit. Why did the vector cross the road? It wanted to be normal. #4 20051025 01:33:08

Re: MonotonicityCool graph .. I thought it would go down for a bit because of the negative terms. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #6 20051028 15:33:52
Re: MonotonicityI should have known better than to make fun of Math in a Math forum. El que pega primero pega dos veces.
