Question
pleas i want a note on;(1) mean value theorem (2) curve sketching (3) cost function and (4) demand function

Answer
Dear innocent:

(1) The mean value theorem states that if a function is continuous on [a,b] then there is some point in the middle of the function that is equal to the average value over the entire region [a,b].

(2) To sketch a curve, usually it's done in two dimensions in rectangular coordinates named x and y.  The x variable goes on the horizontal axis and the y variable goes on the vertical axis.

(3) Usually the cost function is a basically increasing function with time as the x variable and cost as the y variable.  Now and then it may decrease in value, but usually it goes up.

(4) The demand function slopes one way and the supply function slopes the other.  The ideal production is at the point that maximizes return, which is usually near where the two curves cross.  It is not right on that point except in perfect circumstances.

Expertise

Any kind of calculus question you want. 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 25 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 7,500 questions on the PC. Well over 2,000 of them have been in calculus.

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 from all over the world.
