WebView Tan and Cot Graphs PPT2-3.pdf from MATH 1503 at The University of Oklahoma. One definition for tangent is tan x = sin x cos x . Notice that the denominator is cos x. This indicates WebLet's first look at the graphs of tan x and cot x. (Note: the two graphs face each other in opposite directions) Both tangent and cotangent have origin symmetry, and this means they are odd. Algebraic approach Foreknowledge: sin x is odd ( sin ( − x) = − sin ( x) ), cos x is even ( cos ( − x) = cos ( x) ).
