Jan 30, 2015 · A function is even if: #f(-x)=f(x)#. A function is odd if: #f(-x)=-f(x)#. In this case: #y=tan(-x)=sin(-x)/cos(-x)=(-sin(x))/cosx=-sinx/cosx=-tan(x)#, for the simmetry of sinus and cosinus.
May 30, 2024 · Odd Function: Since tangent function satisfies the property tan(-θ) = -tan(θ), hence it is an odd function. Vertical Asymptotes: Tangent function is defined as a vertical asymptote at any odd multiple of π/2 radians (90 degrees).

Feb 28, 2015 · Except for a very few special angles the values of the sine, cosine , and tangent functions are non-integer . A function is called even if its graph is symmetrical about the y_axis, odd if its graph is symmetrical about the origin.
Therefore, tangent is an odd function. We can further analyze the graphical behavior of the tangent function by looking at values for some of the special angles, as listed in Table 2.3.1. These points will help us draw our graph, but we need to determine how the graph behaves where it is undefined.
