Secant equals math. In fact most calculators have no button for them and software function libraries do not include them. Cotangent is the reciprocal of tangent. The cosecant of denoted is we summarize information about the domain and range of the six trig functions. The secant of denoted is definition.

1 cot 2 a csc 2 a displaystyle 1 cot 2 a csc 2 a these formula can then be rearranged so that the 1 is on its own on one side of the equals sign i e from the tan relation. In a right triangle the secant of an angle is the length of the hypotenuse divided by the length of the adjacent side. Secant sec trigonometry function see also secant of a circle. When solving right triangles the three main identities are traditionally used.

Secant is the reciprocal of cosine. However the reciprocal functions secant cosecant and cotangent can be helpful in solving trig equations and simplifying trig identities.
