Domain Of Secant Graph

The lower bound of the range for secant is found by substituting the negative magnitude of the coefficient into the equation.

Domain of secant graph. In this video lesson we talk about the graphs of the three other trigonometric functions of cosecant secant and cotangent. Function graph is depicted below fig. As with tangent and cotangent the graph of secant has asymptotes.

The cosine graph crosses the x axis on the interval. The graphs of tan x cot x sec x and csc x are not as common as the sine and cosine curves that we met earlier in this chapter. Thus the domain is all x except 3π 2 π 2 π 2 3π 2.

In trig speak the rule looks like this in degrees. Domains of cosecant and secant. X r and x nπ n z.

As cot x is the reciprocal of tan x its domain is the set x. Since the cosine has range 1 1 the range of the secant is 1 u 1. The domains of cosecant and secant are restricted you can only use the functions for angle measures with output numbers that exist.

X r and x 2n 1 π 2 n z domain of cosecant. As sec x is the reciprocal of cos x its domain is the set x. The domain is all values of that make the expression defined.

X r and x nπ n z domain of cotangent. You can graph a secant function f x sec x by using steps similar to those for tangent and cotangent. This is because secant is defined as.
