This video shows a middle school Khmer-American girl demonstrating algebra radical equation problem solving strategies.
In this video I go over a quick derivation into the arc length formula for polar curves. The derivation involves using the already derived formula for arc length in parametric form, which I derived in my earlier videos, but then converting the polar curve into the well known pair of parametric equations: x = rcosϴ…
What Is Gravity? Newtonian Gravity vs General Relativity What is gravity? It keeps you on the ground and the planets orbiting the sun. But do you really know what gravity is? If you haven’t heard of General Relativity, chances are you don’t know our current theory on what gravity is. Be sure to subscribe!
