SOLUTION: Find the domain of y=x/cosx I know that cos(x)can't equal zero and that means x can't be pi/2, 3pi/2, etc. Just not sure on how to notate the domain for this one.

Question 482541: Find the domain of y=x/cosx
I know that cos(x)can't equal zero and that means x can't be pi/2, 3pi/2, etc.
Just not sure on how to notate the domain for this one.

You could notate it something like

(The () should be {}, LaTeX interprets curly braces differently so I could not type them without changing the {} to a string).

This is set-builder notation representing "the set of all real x such that for all non-integer k, x = (2k+1)pi/2."
