<font face="Times New Roman" size="+2">


The periodicity of *[tex \Large a\,+\,b\cdot f(nx\,+\,p)] is *[tex \Large \frac{2\pi}{n}], where *[tex \Large f] is *[tex \Large \sin], *[tex \Large \cos], *[tex \Large \csc], or *[tex \Large \sec].


The periodicity of *[tex \Large a\,+\,b\cdot f(nx\,+\,p)] is *[tex \Large \frac{\pi}{n}], where *[tex \Large f] is *[tex \Large \tan] or *[tex \Large \cot]


You can do your own arithmetic.
