# Cofunction Calculator

Trigonometry is the subject of our Cofunction Calculator. In essence, there are six functions in trigonometry that fully define the relationships between angles and sides of a triangle. We put them into pairs since they are interconnected: sin and cos, tan and cot, sec and csc. The cofunction identities calculator shows how sine, cosine, tangent, cotangent, secant, and cosecant relate to each other. The trig function of an angle is equal to the cofunction of the angle's complement. Check out other calculators on calconcalculator.com!

## How to find a cofunction?

The specific formula for converting between sine and cosine, tangent and cotangent, secant and cosecant are provided by cofunction identities. Using this definition, we may compute back and forth between cofunctions: The value of an angle function equals the value of the complement's cofunction. This function is a "reciprocal" or inverse function in our calculator. To discover a function, you must first determine its reciprocal value. Identity sums and differences for sinusoidal and tangent functions are calculated using identity configurations.

If you're seeking for a faster way to tackle basic to complex sin, cos, and tan problems, you've come to the right place. We've covered all of the fundamental and conventional trigonometry topics here, including sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc), so you can perform the calculations quickly. So, to obtain a strong grasp of the idea, consider using these free online trigonometry calculators during homework and tasks.

## Cofunction calculator - degrees and radians

Similarly, the tangent and cotangent functions and the secant and cosecant functions are cofunctions. If the radian measure of an acute angle is variable u, then the angle measure using the radian measure /2 – u is complementary to u. When the variable u is a real number or the radian, the cofunction formulas in degrees are equivalent to 90° - u. (a measure of an angle). The cofunction formula in π/2 – u, radians is given variable u as a real number or an angle's radian measure.
