## How do you tell if a right triangle is sin cos or tan?

In any right angled triangle, for any angle:

1. The sine of the angle = the length of the opposite side. the length of the hypotenuse.
2. The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.
3. The tangent of the angle = the length of the opposite side. the length of the adjacent side.

## What is the formula for sin cos and tan?

Sin Cos Tan Formula Sine θ = Opposite side/Hypotenuse = BC/AC. Cos θ = Adjacent side/Hypotenuse = AB/AC. Tan θ = Opposite side/Adjacent side = BC/AB.

What is the equation for a sine graph?

The equation of a basic sine function is f(x)=sinx. In this case b, the frequency, is equal to 1 which means one cycle occurs in 2π. If b=12, the period is 2π12 which means the period is 4π and the graph is stretched.

### How do you use CAH?

The hypotenuse is always opposite the right angle. The sine of an angle is equal to the side opposite the angle divided by the hypotenuse….Sohcahtoa Calculator.

Soh… Sine = Opposite / Hypotenuse
…cah… Cosine = Adjacent / Hypotenuse
…toa Tangent = Opposite / Adjacent

### How do I know if I have SOH CAH TOA?

SOHCAHTOA is a mnemonic device helpful for remembering what ratio goes with which function.

1. SOH = Sine is Opposite over Hypotenuse.
2. CAH = Cosine is Adjacent over Hypotenuse.
3. TOA = Tangent is Opposite over Adjacent.

How do you find the cosine of a triangle?

In any right triangle, the cosine of an angle is the length of the adjacent side (A) divided by the length of the hypotenuse (H). In a formula, it is written simply as ‘cos’.

#### What are the trigonometric ratios of sin cos tan tan and cos?

The trigonometric ratio table for six functions like Sin, Cos, Tan, Cosec, Sec, Cot, are: Trigonometric Ratios/ angle= θ in degree 0 ° 30 ° 45 ° 60 ° Sin θ 0 1/2 1/√2 √3/2 Cos θ 1 √3/2 1/√2 1/2 Tan θ 0 1/√3 1 √3 Cosec θ ∞ 2 √2 2/√3

#### What is the importance of graphing sine cosine and tangent?

Graphing sine, cosine and tangent are fundamental skills and concepts required to analyze and graph more complicated trigonometric functions, and even to understand the short cuts for transformations of trigonometric functions.

What is the sin and cos function of an angle?

Sine function of an angle is the ratio between the opposite side length to that of the hypotenuse. From the above diagram, the value of sin will be: Cos of an angle is the ratio of the length of the adjacent side to the length of the hypotenuse. From the above diagram, the cos function will be derived as follows.

## What are the graphs of the three trigonometry functions?

Below are the graphs of the three trigonometry functions sin x, cos x, and tan x. In these trigonometry graphs, x-axis values of the angles are in radians, and on the y-axis, its f (x) is taken, the value of the function at each given angle. The combined graph of sine and cosine function can be represented as follows.
