What are the main formulas of trigonometry?
Basic Trigonometric Function Formulas
- sin θ = Opposite Side/Hypotenuse.
- cos θ = Adjacent Side/Hypotenuse.
- tan θ = Opposite Side/Adjacent Side.
- sec θ = Hypotenuse/Adjacent Side.
- cosec θ = Hypotenuse/Opposite Side.
- cot θ = Adjacent Side/Opposite Side.

What are the basics of trigonometry?
Basic Trigonometry involves the ratios of the sides of right triangles. The three ratios are called tangent, sine and cosine. It can then be extended to other ratios and Trigonometry in the Cartesian Plane .
What are the rules for trigonometry?
There are 3 trigonometry rules which are: Sin θ = O/H Cos θ = A/H Tan θ = O/A (when there is no hypotenuse)
What is the equation for trigonometry?
The general form for a trig function. The general form for the equation of a trigonometry function is y = Af [B (x + C)] + D, where. f represents the trig function. A represents the amplitude, or steepness.
What is the formula for cos sin Tan?
The functions of sin, cos and tan can be calculated as follows: Sine Function: sin(θ) = Opposite / Hypotenuse Cosine Function: cos(θ) = Adjacent / Hypotenuse Tangent Function: tan(θ) = Opposite / Adjacent
