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 I'm having difficulty setting these equations up. Any help would be greatly appreciated!

The length, L, of a rectangle is decreasing at the rate of 2cm/second while the width, W, is increasing at the rate of 2cm/second. When L = 12cm and W = 5cm, find the rates of change of the area, the perimeter, and the lengths of the diagnol of the rectangle.
Answer dL/dt = -2, dW/dt = 2, L=12, W=5
Area is A=WL, perimeter is P=2W+2L, lengths of the diagonal of the rectangle is C=Sqrt(W²+L²).
Note that A, P, and d are all functions of W and L. Using the chain rule, find dA/dt, dP/dt, and dC/dt.
