“How do I write the equation of a circle with center (5,-7) and radius 9 units?”
I would write this equation so it's similar to how the equation of an ellipse would look. The denominators will be the same. And you could write this in different ways, but I think this way clearly …
Tutoring Physics, Dot Products and Cross Products Return
We looked at induced currents, loops, magnetic fields. Spent some time on the right hand rule. Also looked at the difference between dot products and cross products. They are important for the …

Tutoring Calculus, Series, Sequences, Improper Integrals and Limits
We focused on series and sequences and looked a bit at improper integrals. All of these are connected to limits. If something diverges, which is easier to determine than convergence, you simply say …

Two Kinematic Equations Illustrated
I drew this diagram of two equations in physics. I used different colors to show different things. The letter x stands for position, the letter v stands for velocity, the letter a stands for …
