Expertise

Most ordinary differential equations.

Experience in the area

I have taken Differential Equations at OSU. Occasionally I have assisted people with questions on the subject.

Publications

In the paper where MS students publish a thesis on shock waves and rarefaction fans.

Education/Credentials

MS at OSU in Mathemematics. MS at OSU in Mathematical Science.

Awards and Honors

Graduation with honors for my BS and MS.

Past/Present Clients

I answered many questions at OSU, down in south seattle at a college, at a church in Corvallis, OR, as Safeway in Washington, and many other areas. I have answered over 7,500 right here, but only a little over 150 of them have been in differential equations.

What do you like about this subject?

I have heard that it seems like fun to differentiate on contact. Perhaps it makes people oscillate wildly. Q

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

I have learned how to solve 5th order differential equations, and strive to learn more about methods for solving other types of diffEQ's.

Something interesting about this subject that others may not know:

Id doesn't take much to make solving differential equations quite complicated, even 1st order ones.

Something controversial or provocative about this subject

Some write the derviative of y as y' while other write it as dy/dx. That may not be that controlversial, but at least this block has been filled.

To determine the amount needed for college, use the following 96 periods (# of months iin 8 years), 0.5% interest rate each month, and $1,000.00 amount per period. We'll use the starting year

I would put the function in Excel and test out x values. I get -7 -167 -6 -124 -5 -87 -4 -56 -3 -31 -2 -12 -1 1 0 8 1 9 2 4 3 -7 Now if the equation is taken as -3(x² - 4x/3 - 8/3), completing

2012-03-16 Linear v. Nonlinear PDEs:

Q1. I believe that homogenous equations were equations that had no u(x,t) is them. What we have is sin(x)(du/dt) - t²(d²u/dx²) = 0. By definition, the solution is homogeneous. Q2. This is a linear

2012-03-14 Newton Raphson Method:

The Newton-Raphson method says to solve for x1 by the following equation: x1 = x0 - f(x0)/f'(x0). Assuming the equation is 3x³ - 2x² - x - 10 { the + before the x is ignored since a + times a - is

2012-02-17 Mathematics:

Take (1-x)dy added to both sides, giving (1+y)dx = (1-x)dy. Divide both sides by 1+y, giving dx = (1-x)/(1+y) dy. Divide both sides by (1-x), giving (1/(1-x)) dx = (1/(1+y)) dy. Integrate both
