Which functions have a range of all real numbers ? check all that apply. a. y=csc x b. y=sec x c. y=tan x d. y= cot x

None of these. All of these functions are defined as ratio of trigonometric functions.

Trigonometric functions have infinite zeroes, so when you put them in the denominator, they lead to infinitely many points of ill-definition.

Specifically, we have:
