    1. A tangent function has symmetry about the origin (0,0) between the interval of -90 deg and +90 deg.

    If you look at the graph of a tan(x) carefully enough, it's not hard to notice the graph stays the same you mirror it to the y-axis and then again to the x-axis. This is called Symmetry About the Origin.

    But please keep in mind there is a x-range (interval) restriction because of the infinity issue... tan(90 degree) = oo/0 = +oo infinity...

    願對您有幫助

    For any given tangent function, -f(x) = f(-x), which by definition is an odd function.
