## A Simple Presentation of Derivation of Harmonic Oscillator and a Different Derivation of the Pythagorean Theorem

**Authors:** Janko Kokosar

Sergio Rojas wrote an article about derivation of classical harmonic
oscillator. This derivation is more clear for students. Some sentences are added here
which still more visualize his derivation. A derivation of the Pythagorean theorem from
kinetic energy law is added. Such derivations are a way, how to improve visualization
of fundamental theories of physics, and to visualize their derivations and problems.
