Graph of the tangent function ( = )
• If you notice, the range of the tangent function is (−∞, ∞) and the domain
is { | ≠ + , ℎ }
2
• The x intercepts are always in the form of
• The period is
• The tangent will be zero wherever the numerator (sine) is zero
• The tangent will be undefined wherever the denominator (cosine) is zero
• The graph of the tangent function has vertical asymptotes at values of in
the form of = +
2
• Since the graph is symmetrical about the origin, the function is an odd
function
