# Math Help - Period of f(x)

1. ## Period of f(x)

my question is what is the period of f(x)= cot(119x)+sec(112x)? I do not understand what to do. I know that cotangent is pi/2 and secant is 2pi/2, but cant get the right answer

Solution:

Given f(x)= cot(119x)+sec(112x)
we can write it as cot(119(x+π/7))+sec (112(x+π/7))
there for the period is π/7
