Unlock the power of trigonometry with our online calculator. Quickly find sine, cosine, tangent, and their inverse values (arcsin, arccos, arctan) for any angle or ratio. Ideal for math students, engineers, and anyone needing quick trig solutions in degrees or radians.
Formula:
Trigonometric functions relate the angles of a right-angled triangle to the ratios of its sides. For an angle θ:
- Sine (sin θ) = Opposite / Hypotenuse
- Cosine (cos θ) = Adjacent / Hypotenuse
- Tangent (tan θ) = Opposite / Adjacent
The Inverse Trigonometric Functions (arcsin, arccos, arctan) work in reverse: they take a ratio and return the corresponding angle.
- Arcsine (sin-1 x): Returns the angle whose sine is x.
- Arccosine (cos-1 x): Returns the angle whose cosine is x.
- Arctangent (tan-1 x): Returns the angle whose tangent is x.
