Cofunction Identities YouTube
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}\).

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.

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. Scroll down the page for more examples and solutions on how to.

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.

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.

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 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)

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.

The cofunction identities show the relationship between sine, cosine, tangent, cotangent, secant, and cosecant. The value of an angle's trig function equals the value of the angle's complement's cofunction. We refer to the sine and cosine functions as cofunctions of each other.

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.
