The armspan (fingertip to fingertip) is approximately the height.Without new words, humans are hard to describe: “There’s a sphere at the top, which gets scratched occasionally” or “Two elongated cylinders appear to provide locomotion”.Īfter creating specific terms for anatomy, Bob might jot down typical body proportions: Imagine Bob The Alien visits Earth to study our species. Trig functions are percentages to the three shapes.Visualize a dome, a wall, and a ceiling.I think you deserve better, and here’s what made trig click for me. And “TOA” evokes the stunning beauty of an abstract ratio. The rest of us, with organic brains half-dedicated to vision processing, seem to enjoy imagery. Sure, if you’re a math robot, an equation is enough. TOA explains the tangent about as well as $x^2 + y^2 = r^2$ describes a circle. It does not store any personal data.Trig mnemonics like SOH-CAH-TOA focus on computations, not concepts: The cookie is set by the GDPR Cookie Consent plugin and is used to store whether or not user has consented to the use of cookies.

Inverse Trig functions are also notated as: The definitions of the inverse trig functions are: The periods for each of these trig functions are: The ranges of values possible for each of these functions are: The possible angle input for each function is defined below: The other side next to theta will be referred to as adjacent. The side opposite theta will be referred to as opposite.

The longest side of the triangle is the hypotenuse.

A right triangle has one angle that is 90 degrees. The functions sine, cosine, and tangent can all be defined by using properties of a right triangle. To define the trigonometric functions of an angle theta assign one of the angles in a right triangle that value.
