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 Which of the following is the best integration technique to use for ∫2x(x2 + 1)5 dx?
A) The product rule.
B) The chain rule.
C) The power rule.
D) The substitution rule
What is the value of R(g) = f(g)/h(g), f (-4) = 2, h(-4) = 0, f '(-4) = 6, h'(-4) = 3.
A) 0
B) ½
C) 2
D) This is indeterminate.
Answer 1) As I look at what we are integrating, the first thing that pops into my head is to let u = x² + 1, du = 2x dx, which is the chain rule. However, actual integration is done on ∫u^5 du,
so the integration, in my opinion, is done with the power rule.
The chain rule is used to put it in the form where it can be integrated, but that is not the actual integration.
2) For R(g) = f(g)/h(g), they give us all the values we need to determine the value when g is -4. However, no where does the problem state that g = -4, so I would say the answer were (D).
