How many trigonometry are there?
six trigonometric ratios
The six trigonometric ratios of a right angle triangle are Sin, Cos, Tan, Cosec, Sec and Cot. They stand for Sine, Cosine, Tangent, Cosecant, Secant, and Cotangent respectively.
What is the rule for trigonometry?
Sin θ / Cos θ. This means that: Sin θ = Cos θ × Tan θ and. Cos θ = Sin θ / Tan θ….Introducing Sine, Cosine and Tangent.
| Name | Abbreviation | Relationship to sides of the triangle |
|---|---|---|
| Sine | Sin | Sin (θ) = Opposite/hypotenuse |
| Cosine | Cos | Cos (θ) = Adjacent/hypotenuse |
| Tangent | Tan | Tan (θ) = Opposite/adjacent |

How to learn trigonometry?
Method 1 Method 1 of 4: Focusing on Major Trigonometric Ideas. Define the parts of a triangle.
What is the formula for trigonometry?
A formula for computing the trigonometric identities for the one-third angle exists, but it requires finding the zeroes of the cubic equation 4×3 − 3x + d = 0, where x is the value of the cosine function at the one-third angle and d is the known value of the cosine function at the full angle.
