Question 823962: Name all values of θ for which y=secθ is undefined. Give the answer in radians.
I read my textbook and I started the problem with secθ= 1/cosθ. I'm not sure what it means when it is "undefined". Does that mean it equals zero? My textbook doesn't really explain this problem that well.
Thanks for your help!

----------------
Undefined usually means a division by zero.
1/0 is undefined, sometimes called infinite.
x/0 is undefined.
------------
sec is undefined when cos = 0.
cos(t) = 0 --> t = pi/2 + n*pi, n = +/- 0,1,2,3...
