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 f(x)= 1/sqrt(1+sin x)
Tell where f is continuous. Give your answer in interval notation.
I know it is continuous unless sqrt(1+sin x)/=0 (not equal to zero) or sin x=-1. My problem lies in how to put it in interval notation. I have (-infinity,-pi/2)and((3pi/2),+infinity). How do I show that they recur every 2pi afterwards?
Answer I'd not try to write it with parenthesis.
I'd put all 'The function f is continuous at all real numbers except for where x=2nπ + 3π/2 for all integers n.'
By the way, π is really pi. Does it show up like that?
