What is concavity of a graph
👉 Learn how to determine the concavity of a function. A function is said to be concave up (convex) if the graph of the curve is facing upwards and the function is said to be concave down (concave) if the graph is facing down. To test for...

Using Convex Lenses to Magnify
Using animation and real world examples, this video explores the change in kinetic energy of particles with heating and cooling that produces expansion and contraction and change in density in matter. Students will observe and come to...

Hollow-face illusion, animation.
This is an optical illusion where the perception of a concave (hollow) mask of a face appears as a normal convex (protruding) face. This is because the brain has a strong bias for seeing faces as convex, which counteracts competing depth...
