What is the cofunction calculator?
The cofunction calculator is here to find the cofunction of the trigonometric function you choose for a given angle between 0 and 90 degrees.
What is tan cofunction?
Using the cofunction equations for sine and cosine: sin(θ) / cos(θ) = cos(90o – θ)/sin(90o – θ). But cosine / sine is cotangent, giving cos(90o – θ) / sin(90o – θ) = cot(90o – θ). Thus, tan(θ) = cot(90o – θ). If your calculator does not have a cotangent button, you can compute cot(-15o) as 1/tan(-15o).
What is the cofunction of sin 35?
0.5736
Sin 35 degrees is the value of sine trigonometric function for an angle equal to 35 degrees. The value of sin 35° is 0.5736 (approx).
What is cofunction of cot?
Cofunction Identities, degrees sin (90° – x) = cos x. cos (90° – x) = sin x. tan (90° – x) = cot x. cot (90° – x) = tan x. sec (90° – x) = csc x.
What is the cofunction of Cos 35?
0.8192
∴ cos 35° = 0.8192.
What is cot cofunction?
What is the cofunction of sin 42?
1.49447
Since the cosecant function is the reciprocal of the sine function, we can write sin 42° as 1/cosec(42°). The value of cosec 42° is equal to 1.49447.
What is the cofunction of sin 60?
Explore the pattern for Cofunctions
| θ | sin( θ ) | θ – 90 |
|---|---|---|
| 50 ° | sin(50 ) = 0.76604444311898 | 90 – 50 = 40 ° |
| 60 ° | sin(60 ) = 0.86602540378444 | 90 – 60 = 30 ° |
| 70 ° | sin(70 ) = 0.93969262078591 | 90 – 70 = 20 ° |
| 80 ° | sin(80 ) = 0.98480775301221 | 90 – 80 = 10 ° |

What is the cofunction theorem?
Cofunction Theorem. Proof: Let the point on the unit circle have coordinates and arc length , measured counterclockwise from the point . Define point to be the point on the unit circle whose arc length is , measured counterclockwise from the same point. Then the coordinates of point are .
What is the cofunction of sin?
cos(90° – A) = sin A. Using substitution:cos(90° – 67.4°) = sin 67.5°. cos(22.6°) = sin(67.5)°. Therefore, the value of cosine B is equal to sine A which is the cofunction and complement of B. The process remains the same whether you are in degree mode or radian mode.
What are cofunction identities?
The cofunction identities show the relationship between sine, cosine, tangent, cotangent, secant and cosecant. The value of a trigonometric function of an angle equals the value of the cofunction of the complement. Recall from geometry that a complement is defined as two angles whose sum is 90°.
