Is SOH CAH TOA a mnemonic?
SOHCAHTOA is a mnemonic device used to remember the ratios of sine, cosine, and tangent in trigonometry.
What does Sohcahtoa stand for?
“SOHCAHTOA” is a helpful mnemonic for remembering the definitions of the trigonometric functions sine, cosine, and tangent i.e., sine equals opposite over hypotenuse, cosine equals adjacent over hypotenuse, and tangent equals opposite over adjacent, (1) (2)
What leg is considered the hypotenuse?
A right triangle consists of two legs and a hypotenuse. The two legs meet at a 90° angle and the hypotenuse is the longest side of the right triangle and is the side opposite the right angle.
What does Sohcahtoa mean in math?
What does cast mean in trigonometry?
The CAST Rule. The CAST Rule says that in quadrant I all three of sinθ, cosθ, tanθ are positive. In quadrant II, only sinθ is positive, while cosθ, tanθ are negative. In quadrant III, only tanθ is positive, while sinθ, cosθ are negative.
What are the Trig rules?
The three main functions in trigonometry are Sine, Cosine and Tangent….Sine, Cosine and Tangent.
| Sine Function: | sin(θ) = Opposite / Hypotenuse |
|---|---|
| Cosine Function: | cos(θ) = Adjacent / Hypotenuse |
| Tangent Function: | tan(θ) = Opposite / Adjacent |
Should I memorize trig identities?
Many trig classes have you memorize these identities so you can be quizzed later (argh). You don’t need to memorize them, you can work out the formula in about a minute.
