What Is An Cofunction Calculator?

A cofunction calculator is an instrument used to calculate a function's cofunction values of trigonometric angles. This calculator gives you a detailed and accurate outcome for your input.

A connection between two trigonometric functions which are connected by complementary angles is known as cofunction in trigonometry. We can also say that the cofunction of an angle is its complement trigonometric function.

When working with angles in trigonometry, understanding equivalent angles is also important. You can use our Coterminal Angle Calculator to find angles that share the same terminal side.

How to Calculate Cofunctions:

Let's consider a few examples to learn how to find cofunctions of trigonometric functions.

Example 1:

Angle = 10, In terms of degree, find the cofunction of sin(θ) = ?

Step 1: First write the given data

θ = 10, cofunction of sin(θ) = ?

Step 2:

Formula for cofunction of sin(θ)

sin(θ) = cos(90- θ)

Step 3: Substitute values:

sin(10) = cos(90- 10)

sin(10) = cos(80)

So, cofunction of sin(10) is cos(80)

FAQS:

What are the cofunction Identities?

Cofunction identities are mathematical connections among trigonometric functions of complementary angles For instance:

sin(θ) = cos(90 - θ)

cos(θ) = sin(90 - θ)

How to convert degree to radian?

To convert degrees to radians we use the formula given below

Is there a cofunction calculator that can handle both radians and degrees?

Yes! In our calculator, you may enter values in both degrees and radians using our cofunction calculator. Our device best meets your demands.

Yes, our cofunction calculator is a web-based device available through our site, so you will require an internet connection to use it.

What are the basic Cofunctions Formulas?

Some basic function cofunction pairs are:

FUNCTION	COFUNCTION PAIR
sin	sin(x) = cos(90° - x)
cosine	cos(x) = sin(90° - x)
tangent	tan(x) = cot(90° - x)
cotangent	cot(x) = tan(90° - x)
Secant	sec(x) = csc(90° - x)
cosecant	csc(x) = sec(90° - x)
