Cofunction Calculator
Result
Cofunction Calculator The Cofunction Calculator applies the cofunction identities, which relate a trig function of an angle to the complementary function of its complement (90° − θ). Enter an angle and function. — free online calculator.
Formula
- Cofunction Calculator calculates its result from Angle θ, Cot, Csc. It uses the formula sin θ = cos(90° − θ), tan θ = cot(90° − θ), sec θ = csc(90° − θ). Change any input to recalculate the result instantly.
- The main inputs are Angle, Function. Enter them in the units and format shown in the calculator.
- Keep comparable quantities in compatible units whenever the formula combines or compares them.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Cofunction
- Angle: 30
- Function: sin
Using Angle θ = 2, Cot = 3, Csc = 4, the calculated result is 352.
