How To Learn Trigonometry Intuitively – BetterExplained
TOA explains the tangent about as well as x2+y2=r2 describes a circle. Sure, if you’re a math robot, an equation is enough. The rest of us, with organic brains half-dedicated to vision processing, seem to enjoy imagery. And “TOA” evokes the stunning beauty of an abstract ratio.
Trig mnemonics like SOH-CAH-TOA focus on computations, not concepts: TOA explains the tangent about as well as $x^2 + y^2 = r^2$ describes a circle. Sure, if you’re a math robot, an equation is enough. The rest of us, with organic brains half-dedicated to vision processing, seem to enjoy imagery. And “TOA” evokes the stunning beauty of an abstract ratio. I think you deserve better, and here’s what made trig click for me. Visualize a dome, a wall, and a ceiling Trig functions are percentages to the three shapes Motivation: Trig Is Anatomy Imagine Bob The Alien visits Ear
