# Math Help - Question on transformed tan function (about my notes - not involving a problem)

1. ## Question on transformed tan function (about my notes - not involving a problem)

Under "Properties of the transformed tangent function #3," I don't get the notation for the domain. Can someone elaborate in great detail for me please?

It means that the domain is $\mathbb{R}$ except the set of reals x such that there exists $n \in \mathbb{Z}$ such that $b(x-h) = (2n+1)\frac{\pi}{2}$
3. In other words, everywhere except where the argument of tangent is an odd multiple of $\pi/2$, since tangent is not defined there.
