Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. In trigonometry, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. cot θ equals ${\displaystyle \frac{1}{\mathrm{tan}\theta }}$ or ${\displaystyle \frac{\mathrm{cos}\theta }{\mathrm{sin}\theta }\text{. cotangent cot ctg The trig function cotangent, written cot θ. The x -intercepts of the graph of y = tan (x) are the asymptotes of the graph of y = cot (x). All credits of this video belong to me. This means that at any value of x, the rate of change or slope of cot (x) is –csc2(x). This is the reciprocal of the trigonometric function 'tangent' or tan (x). The asymptotes of the graph of y = tan (x) are the x -intercepts of the graph of y = cot (x). The points labeled 1, Sec (θ), Csc (θ) represent the length of the line segment from the origin to that point. The trigonometry identity is cot (x - y) = (cot x cot y + 1)/ (cot y - cot x).

Hi , thanks! the question was : did the funtion tan (x) ,cot (x) has a symmetry axis , I tried to look at the function graph and see if there is a symmetry, i think there isn't one but I'm not sure how to get the full picture, and a good explanation why this is true without relying only on the function graph. For more on this see Derivatives of trigonometric functions together with the derivatives of other trig functions. The cotangent function is equivalent to the reciprocal of the tangent function, that is, ${\displaystyle \frac{1}{\mathrm{tan}x}}=\mathrm{cot}x$.
