Expert Profile: Scotto

Expertise: Any kind of mathematics (algebra, geometry, trigonometry, matrices, calculus, linear approximation, finite differences, linear regression, linear programming, numerical analysis, probability, statistics, etc.). I also have answered some questions in Physics, Chemistry, and Biology. I would like to volunteer in all areas of Mathematics, not just calculus, and the other three courses that were mentioned.

Experience in the area
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 around 2000 questions on the computer in this language and 1000's of questions in college.

Education/Credentials
I received honors in both my BS and MS degree from Oregon State University.

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.

Past/Present Clients
My past clients have been students at OSU, students at the college in South Seattle, people from my church, and people like you.

What do you like about this subject? Its fun for me to do when I fall asleep - called date-powers. Like say it was the 21st. That's 3*7. 3^4=81. 7^4=2401. 3^2*7^2=441. 3^8=6561. 7^8=5,764,801. Then to do a little more, I look at all combinations of 8 numbers using 3 and 7. Having done that, I then try 9 of them. You know, 3^9 = 19,684; 3^8*7=45,927; 3^7*7^2=107,163; etc.

What do you still hope to achieve/learn in this field? Doing even more mathematics. Maybe somebody wants me to do this for work, but until then ...

Something interesting about this subject that others may not know: The natural log of e is 1 [ ln(e)=1 ], but did you know that e=2.71828182845905... or that pi, the usual 3.14, is really 3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510 58209 74944 59230 78164 ...

Something controversial or provocative about this subject Some people have controversies in statistics. When they say average, there are three different ways to do it. Some are interested in (max-min)/2, some are interested in the midway point, and some are actually interested in the true average (add 'em up and divide by n). This might not actaully be controversial, but at least you have read something here.

2009-07-02 Calc. or Numeric Analysis: 1. Lim as x->+0 of (cos x - e^x)/(ln(1+x^2) L'Hospital's Rule says to take the derivative of the numerator and the denominator, and then see what the quotient comes out to be. The derivative of...

2009-06-25 integration: You can't find the derivative of integral, but only a numerical approximation. For derivatives, use a very small difference in x values to find the y value. For integrals, use very small x values between...

2009-06-25 need help on curve sketching: The function is f(x) = (4 - x²)/(x² + 1). To find the derivative, use the quotient rule. That is, (lo d hi - hi d low)/lo sqaured. The first derivative is f'(x) = ((x²+1)(-2x) - (4-x²)(2x))/(x²+1)²...

2009-06-25 calculus: First of all, the function is the function f(x) = √(9-x²)? If it is, then |x| <= 3, for if |x| > 3, then x² > 9, and we can't take the squareroot of a negative number. To start on the graph...
