A nonlinear algebraic equation. I am solving this as a system of equations.

I am attempting to solve an ODE using a Calculus add-in for Excel. I am an industry professional and I have not even thought about Differential Equations in 8 years. The equation that I am attempting to solve is in the form: (1) The ODE solver that I am using solves equations of the form...

Homework Statement Find the iterated integral: \int\int(2x+y)^{-2}dydx The first integral is from 3 to 4 and the second is from 2 to 3. Homework Equations The Attempt at a Solution My first thought would be to do u-substitution, but wouldn't that cause problems when trying to differentiate...

Homework Statement A charge is placed on the x-axis (q=+7.00 \muC, x=0.600 m), and another charge is placed on the y-axis (q=+9.00 \muC, x=0.400 m). A third charge (q=-6.00 \muC, m= 5.00 x 10^{-8} kg) is placed at the coordinate origin. If the charge at the origin were free to move, what would...
