Clearly, cos ( 20 ∘) = 0.9 and sin ( 70 ∘) = 0.9. In other words, cos ( 20 ∘) = sin ( 70 ∘) if 20 ∘ and 70 ∘ are complementary. Here, the equation cos ( 20 ∘) = sin ( 70 ∘) is also known as the cofunction identity. The cofunction identities establish the connection between the trigonometric functions.

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.

The cofunction identity for sine can be expressed as the mathematical equation sin (theta) = cos (pi/2-theta). What is the cofunction of CSC? CSC is an abbreviation for the trig function.

cos = sin Pythagorean Identities Consider a point on the unit circle: 6 y P(x; y) = (cos ; sin ) x = tan 1 = cot which leads to triangle 1 sin cos Using the Pythagorean theorem, we see that (memorize this one): cos2 + sin2 = 1 Derive two other identities from the one we have memorized: Divide by cos2 : cos2 cos2 sin2

The cofunction identities are summarized in Table 7.2.2. Table 7.2.2. sinθ = cos(π 2 − θ) cosθ = sin(π 2 − θ) tanθ = cot(π 2 − θ) cotθ = tan(π 2 − θ) secθ = csc(π 2 − θ) cscθ = sec(π 2 − θ) Notice that the formulas in the table may also justified algebraically using the sum and difference formulas.

These are called cofunction identities because the functions have common values. These identities are summarized below. sin θ = cos ( 90 ∘ − θ) cos θ = sin ( 90 ∘ − θ) tan θ = cot ( 90 ∘ − θ) cot θ = tan ( 90 ∘ − θ) Example 1.8. 1. Find the value of sin 45 ∘ using a cofunction identity.

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.

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 identities are trigonometric identities that show the relationship between trigonometric ratios pairwise (sine and cosine, tangent and cotangent, secant and cosecant). We use the angle sum property of a triangle to derive the six cofunction identities.

What are the Co-function 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 (90° - A) cos A = sin (90° - A) sin A = cos B, if A + B = 90° sec A = csc (90° - A) csc A = sec (90° - A) sec A = csc B, if A + B = 90° tan A = cot (90° - A) cot A = tan (90° - A)
