Sohcahtoa1609

The word "sohcahtoa" comes from trigonometry. It’s a mnemonic technique used to remember the definitions of the three basic trigonometric ratios, namely sine, cosine and tangent. And in 1609, Galileo Galilei invented and built the first telescope. So, Sohcahtoa1609, the name of my YouTube channel, reflects my passion for and interest in science and mathematics.

Science is the most accurate description of reality, the world and history.

The laws of mathematics are clear, logical, consistent and inexorable.

Geometry and trigonometry are the most visual branches of mathematics. That makes it easier to understand what’s going on.

I mainly make YouTube videos about mathematics. However, from time to time, I also make YouTube videos about the English language and computer programming.
