AboutScotto Expertise Any kind of mathematics (calculus, analysis, game theory, linear approximation, finite differences, linear regression, linear programming, numerical analysis, probability, statistics, etc.).
I also have answered some questions in
Physics (mass, momentum, falling bodies),
Chemistry (charge, reactions, symbols, molecules), and
Biology.
Experience Experience in the area: I have tutored students in all areas of mathematics for over 20 years.
Education/Credentials: BSand MS in Mathematics from Oregon State University, where I completed sophomore course in Physics and Chemistry. I received both degrees with high honors.
Awards and Honors: I have passed Actuarial tests 100, 110, and 135.
Publications Maybe not a publication, but I have respond to well oveer 3000 questions on the PC.
That's around 2,000 in basic math and 1,000 in advanced math.
Education/Credentials I aquired well over 40 hours of upper division courses. This was well over the number that were required.
I graduated with honors in both my BS and MS degree from Oregon State University.
I was allowed to jump into a few junior level courses my sophomore year.
Awards and Honors I have been nominated as the expert of the month several times.
All of my scores right now are at least a 9.8 average (out of 10).
Past/Present Clients My past clients have been students at OSU, students at the college in South Seattle,
referals from a company, friends and aquantenances, people from my church, and people like you.
Question what is meant by critical point,stationary point,absolute maximum,local maximum,absolute minimum,local minimum.
how will i calculate all the above in the function f(x)=2-3x.x
Answer A critical point is any of the following:
I don't know what is meant by a, 'staitionary point'.
Absolute max: max over the interval specified,
Absolute min: min over the interval specified,
Local max: max in the area, and
Local min: min in the area.
Is that function suppose to be 2-3x*x? The derivative is -3x^2. This is 0 at x=0. The second derivative is -3, which is negative, which implies that this must be a maximum.
The local and absolute max is at x=0. The min's are at the endpoints on either side of 0. If there are no endpoints, the mins are at x equal plus infinit and minus infinity.
The abosolute max and min again depend on if you have any endpoints in the x values to work with, like x>=-4 or -10<=x<=6.
