What is the domain of sin cos and tan?

all real numbers
Function y=tan(x) is defined as sin(x)cos(x) . The domain of this function is all real numbers except those where cos(x)=0 , that is all angles except those that correspond to points (0,1) and (0,−1) .

What is the period of TANX?

The period of tanx is π . Example: tan π4 and tan(π4+π) have the same value ( 1 ).

What is the domain of Arcsin?

The domain of arcsinx is the interval [−1,1] and it is undefined elsewhere. Within this domain it has range [−π2,π2], and these values as input to sinx produce values in the range [−1,1].

What is the domain of Sinx?

The sine function has no domain restrictions. That means that the domain is (−∞,+∞) .

Where is tan not defined?

Answer and Explanation: The tangent function, tan(x) is undefined when x = (π/2) + πk, where k is any integer.

Is Tan Theta 20 correct?

d) tan θ = 20 is correct since tan θ ∈ R. Thus, option (C) sec θ = ½ is the correct answer.

Is TANX continuous in its domain?

For all a in the domain of tanx (i.e. all real numbers except (2k+1)π2,n∈Z), we have that limx→atanx exists and is equal to tana (this can be easily seen from the graph of tanx). So it appears that tanx is continuous.

Is TANX continuous or discontinuous?

The function tan(x) is continuous everywhere except at the points kπ.
