Question

Which of the functions have a range of all real numbers greater than or equal to 1 or less than or equal to -1? Check all that apply.
A. y = sec x
B. y = tan x
C. y = cot x
D. y = csc x

Answer 1

sec x hv a range of all real number as secx=1/cosx and cos x can be closer to 0.
resulting infinity for secx.
same goes to cosecx too.
tanx hv a range of all real numbers as well. (tanx= sinx/cosx)
and cot x hv a range of all real numbers as well. ( cotx=1/tanx and tanx can reach 0)
