What are the 6 trig functions unit circle?
These six functions and their abbreviations are sine (sin), cosine (cos), tangent (tan), secant (sec), cosecant (csc), and cotangent (cot).
What are the 6 trig functions?
There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).
How do you find 6 circular functions?
10.3: The Six Circular Functions and Fundamental Identities
- The cosine of θ, denoted cos(θ), is defined by cos(θ)=x.
- The sine of θ, denoted sin(θ), is defined by sin(θ)=y.
- The secant of θ, denoted sec(θ), is defined by sec(θ)=1x, provided x≠0.
- The cosecant of θ, denoted csc(θ), is defined by csc(θ)=1y, provided y≠0.
How do you do trig functions on the unit circle?
Unit circle coordinates: The unit circle, showing coordinates and angle measures of certain points. We can find the coordinates of any point on the unit circle. Given any angle t , we can find the x – or y -coordinate at that point using x=cos t x = cos t and y=sin t y = sin t .
What are the domain and range of the six circular functions?
Trigonometric Functions
| Function | Domain | Range |
|---|---|---|
| f(x) = sin ( x ) | (-∞ , + ∞) | [-1 , 1] |
| f(x) = cos ( x ) | (-∞ , + ∞) | [-1 , 1] |
| f(x) = tan ( x ) | All real numbers except π/2 + n*π | (-in , + ∞) |
| f(x) = sec ( x ) | All real numbers except π/2 + n*π | (-∞ , -1] U [1 , + ∞) |
What are the six trigonometric functions and their ratios?
Trigonometric Ratios
- The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).
- sin C = (Side opposite to ∠C)/(Hypotenuse) = AB/AC.
- cos C = (Side adjacent to ∠C)/(Hypotenuse) = BC/AC.
How do you find sin and cos on the unit circle?
Using the unit circle, the sine of an angle t equals the y-value of the endpoint on the unit circle of an arc of length t whereas the cosine of an angle t equals the x-value of the endpoint.
