Trigonometric Functions
| Function | Domain | Range |
|---|---|---|
| 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 , + ∞) |
| f(x) = csc ( x ) | All real numbers except n*π | (-∞ , -1] U [1 , + ∞) |
What is the range of Cos 1 x?
0,π
We denote the inverse function as y=sin−1(x) . It is read y is the inverse of sine x and means y is the real number angle whose sine value is x ….Graphs of Inverse Trigonometric Functions.
| Function | Domain | Range |
|---|---|---|
| cos−1(x) | [−1,1] | [0,π] |
| tan−1(x) | (−∞,∞) | (−π2,π2) |
| cot−1(x) | (−∞,∞) | (0,π) |
| sec−1(x) | (−∞,−1]∪[1,∞) | [0,π2)∪(π2,π] |
Why is the range for COS X 1 1?
The range of a function is all possible output, or y , values. The range of y=cosx is from -1 to 1. In interval notation, the range is [-1,1] * Note that square brackets [ ] are used because because y=cosx can actually equal -1 and 1 ( for example, if you plug in x=π , y=−1 ).
What is the inverse of cos X?
The inverse of the restricted cosine function y= cos x, 0 < x < π, is y= cos -1 x and y = arccos x.
What is the range of cos3x?
The range is −1≤y≤1 – 1 ≤ y ≤ 1 .
What is the domain of sin x and cos x?
The two trigonometric ratios sin x and cos x are defined for all real values of x. So, the domain for sin x and cos x is all real numbers.
What is the domain and range of Cos?
Domain and range of inverse cosine function. The domain for Cos–1 x, or Arccos x, is from –1 to 1, just like the inverse sine function. So the x (or input) values. The range for Cos–1 x consists of all angles from 0 to 180 degrees or, in radians, then you write these expressions as.
What is the range of inverse cosine?
The inverse cosine function is written as cos^-1(x) or arccos(x). Inverse functions swap x- and y-values, so the range of inverse cosine is 0 to pi and the domain is -1 to 1. When evaluating problems, use identities or start from the inside function.
What is the range of Cos?
range of cos x is [-1,1]. For the domain [-1,1] cos x is maximum at 0 and minimum at both -1 and 1.So the range of the given function is [0.5403,1].
What is the domain and range of cosine?
Domains of sine and cosine. The domains of sine and cosine are infinite. which means that theta can be any angle in degrees or radians — any real number. Ranges of sine and cosine. The output values for sine and cosine are always between (and including) –1 and 1.
