7.7 Graphs of Tangent, Cotangent, Cosecant, and Secant Functions Properties of the Tangent Function 1. The domain is the set of all real numbers, except odd multiples of π/2. 2. The range is the set of all real numbers. 3. The tangent function is an odd functions, as the symmetry of the graph with respect to the origin indicates. 4. The tangent function is periodic, with period π.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
