* Sine (sin θ): The ratio of the perpendicular side to the hypotenuse of a right triangle.
*Cosine (cos θ): The ratio of the adjacent side to the hypotenuse of a right triangle.
*Tangent (tan θ): The ratio of the perpendicular side to the adjacent side of a right triangle.
*Cosecant (csc θ): The reciprocal of sine.
*Secant (sec θ): The reciprocal of cosine.
*Cotangent (cot θ): The reciprocal of tangent.
Here are some other trigonometry formulas:
*Pythagorean identity: sin² θ + cos² θ = 1
*Angle addition formula: sin (θ + φ) = sin θ cos φ + cos θ sin φ
*Angle subtraction formula: sin (θ - φ) = sin θ cos φ - cos θ sin φ
*Double angle formula: sin 2θ = 2 sin θ cos θ
*Triple angle formula: sin 3θ = 3 sin θ - 4 sin³ θ
