This video will define a vector and explain magnitude and direction, using example graphs.

“Vectors” will define and explain the use of vectors in physics.

Bendixson's criterion is another method used to disprove the existence of closed orbits. A periodic solution is a type of closed orbit. This theorem only holds for simply connected regions in 2D. The statement is that if on a simply...

These second-order nonlinear differential equations can be written in the form: dx/dt = f(x,y) dy/dt = g(x,y) Got a nonlinear differential equation? No problem, just linearize it! This method approximates the vector field as a linear...

On this episode of Nature League, Adrian asks Brit what would happen if all mosquitoes went extinct. Graphics by Tamar Ziri; Original intro and branding by Matt Gaydos and Maia Ledesma. Special help from Felix and Jane

First we solve for the electric potential along the axis of a uniform thin ring of electric charge. Then we use that electric potential to solve for the electric field at the same location.
