Trigonometry Calculator
Solve for any trigonometric ratio or angle. Switch between degrees and radians and calculate inverse functions instantly.
sin(θ) = Opp/Hyp; cos(θ) = Adj/Hyp; tan(θ) = Opp/Adj
sin(30°) = 0.5
What are the six trigonometric functions?
The primary functions are Sine (sin), Cosine (cos), and Tangent (tan). Their reciprocals are Cosecant (csc), Secant (sec), and Cotangent (cot).
What is the difference between Degrees and Radians?
Degrees and radians are two units for measuring angles. A full circle is 360 degrees or 2π radians (approx 6.283). To convert degrees to radians, multiply by π/180.
What are inverse trigonometric functions?
Inverse functions (like arcsin, arccos, and arctan) are used to find the angle that produces a specific trigonometric ratio.
How do I use SOH-CAH-TOA?
It is a mnemonic for right-angled triangles: Sine = Opposite/Hypotenuse, Cosine = Adjacent/Hypotenuse, Tangent = Opposite/Adjacent.
