Ask A Question

Expertise

I can answer any question in general math, arithetic, discret math, algebra, box problems, geometry, filling a tank with water, trigonometry, pre-calculus, linear algebra, complex mathematics, probability, statistics, and most of anything else that relates to math.

Experience in the area

Experience in the area; I have tutored people in the above areas of mathematics for almost two years in AllExperts.com. I have tutored people here and there in mathematics ever since I received a BS degree almost 25 years ago. I tutored at OSU in the math center for all six years I was there. Most students offering assistance were juniors, seniors, or graduate students. I was allowed to tutor as a freshman. I tutored at Mathnasium for well over a year. I worked at The Boeing Company for over 5 years. I received an MS degreee in Mathematics from Oregon State Univeristy. The classes I took were over 100 hours of upper division credits in mathematical courses such as calculus, statistics, probabilty, linear algrebra, powers, linear regression, matrices, and more. I graduated with honors. Past/Present Clients: College Students at Oregon State University, various math people since college, over 2,000 people ion the PC from the US and rest the world.

Publications

My master's paper was published in the OSU journal. The subject of it was Numerical Analysis used in shock waves and rarefaction fans. It dealt with discontinuities that arose over time. They were solved using the Leap Frog method. That method was used and improvements of it were shown. The improvements were by Enquist-Osher, Godunov, and Lax-Wendroff.

Education/Credentials

Master of Science at OSU with high honors in mathematics. Bachelor of Science at OSU with high honors in mathematical sciences. This degree involved mathematics, statistics, and computer science. I also took sophmore level physics and chemistry while I was attending college. On the side I took raquetball, but that's still not relevant.

Awards and Honors

I earned high honors in both my BS degree and MS degree from Oregon State. I was in near the top in most of my classes. In several classes, I was first. I graduated with well over 50 credits in upper division mathematics.

Past/Present Clients

My clients have been students at OSU, people nearby, and friends with math questions, and several people every day on the PC. Just like you.

What do you like about this subject?

I do it all the time and sometimes in my dreams. Now 11*11*11*11*11*11 = 1,771,561. 1,771,561*11 = 19,487,171. Let me see 19,487,171*11 = 214,358,881. Now 214,358,881*11 is ...uh... 2,357,947,691.

What do you still hope to achieve/learn in this field?

I desire to learn even more about math and find new approaches to old problems.

Something interesting about this subject that others may not know:

The numbers 1 and 2 lead to 5 in two different ways. First, use the numbers 1 and 2 to makes 12, but rather than base 10, take base 3. That is 1*3 + 2 = 5. Second, square them and add them together. This leads to 1^2 + 2^2 = 5.

Something controversial or provocative about this subject

Someone once asked me if 728 = 9^3 - 1^3. I said, yes, but did you know that 728 = 12^3 - 10^3? I don't know if that's provocative...

1. ∫(x^2-3)dx The answer would be to add one to the exponent and divide by new exponent. That is, x^3/3 – 3x + C. 2. The linear speed of a belt that passes round a pulley of radius 150mm

1. Use sin5x = sin(4x+x) = sin4x•cosx + sinx•cos4x, sin3x = sin(4x-x) = sin4x•cosx - sinx•cos4x, cos3x = cos(4x-x) = cos4x•cosx + sin4x•sinx, and cos5x = cos(4x+x) = cos4x•cosx - sin4x•sinx. 2.

2009-11-16 Easy Counting Problem?:

The counting looked good, and, well, I looked over it, and the only eror I think I saw was when the sets were counted. It's easiest to group them in groups of five. A1 D1 G4 D7 A4 5 A1 G4

2009-11-10 Pre-calculus:

To simplify things, note that every factor is divisible by 3. Thus, 3x^3+6x^2-15x-30 = 3(x³ + 2x² - 5x - 10). Next, notice that x²(x+2) makes the first two terms and that -5(x+2) is the last two.

2009-11-09 trig:

There is a trig identity involved here. Note that cos(2Θ) = cos²Θ - sin²Θ. So when cos(2Θ) = 0 is when 2Θ = (1+2n)π, n any integer. In the interval given, Θ is in
