The cofunction identities establish a relationship between trigonometric functions \ (sin\) and \ (cos\), \ (tan\) and \ (cot\), and \ (sec\) and \ (csc\). These functions are known as cofunctions of each other. We can write cofunction identities in terms of radians and degrees because these are the units of angle measurement.

Trigonometric co-function identities are relationships between the basic trigonometric functions (sine and cosine) based on complementary angles. They also show that the graphs of sine and cosine are identical, but shifted by a constant of \ (\frac {\pi} {2}\).

cofunction: Cofunctions are functions that are identical except for a reflection and horizontal shift. Examples include: sine and cosine, tangent and cotangent, secant and cosecant. even: An even function is a function with a graph that is symmetric with respect to the y-axis and has the property that \(f(−x)=f(x)\). identity

What are Cofunction Identities? A function f is cofunction of a function g if f(A) = g(B) when A and B are complementary angles. sin(A) = cos(B), if A + B = 90° sec(A) = scs(B), if A + B = 90° tan(A) = cot(B), if A + B = 90° The following figures give the cofunction identities.

Cofunction Formulas, also known as Cofunction Identities, are a set of trigonometric identities that establish relationships between the trigonometric functions of complementary angles. Complementary angles are two angles whose sum is equal to \(90\) degrees (\(\frac{\pi}{2}\) radians), forming a right angle.
