To obtain the cofunction identityfor tangent and cotangent, begin with the quotient
identity: tan(11'/2 — A) I [sin(11'/2 I A)] / [cos(1'r/2 I A)] Substituting the cofunction
identities cos(1'r/2 I A) I sin A and sin(1'r/2 I A) I cos A gives: tan(11'/2 I A) I cos ...

We can use the cofunction identities to verify the remaining sum and difference
identities. To derive an identity for sin(a 1 b), substitute a 1 b for u in the
cofunction identity sin u 5 cos(90 2 u). sin u 5 cos(90 2 u) 5 5 cos[90 2 (a 1 b)] cos

Cofunction Identities The sine and cosine are called cofunctions, as are the
tangent and cotangent, and the secant and cosecant. There is a special
relationship between each pair of a function and its cofunction. In general, the
function of= the ...
