How to Simplify an Expression Using Co-function Identities

WebCofunction definition, the function of the complement of a given angle or arc: cosθ is the cofunction of sinθ. See more. WebSo sine and cosine are cofunctions, secant and cosecant are cofunctions, and tangent and cotangent are cofunctions. That is how the functions cosine, cosecant, and cotangent got the “co” in their names. The Cofunction Theorem says that any trigonometric function of an acute angle is equal to its co-function of the complementary angle. WebCofunction Identities Worksheets. Cos, cot, and cosec are cofunctions of sin, tan and sec, hence they are prefixed with "co".
