About Trigonometric Functions

Trigonometric functions relate the angles of a triangle to the ratios of its sides. These functions are fundamental in mathematics, physics, engineering, and many other fields.

Basic Trigonometric Functions
  • Sine (sin): In a right triangle, the sine of an angle is the ratio of the opposite side to the hypotenuse.
  • Cosine (cos): The cosine of an angle is the ratio of the adjacent side to the hypotenuse.
  • Tangent (tan): The tangent of an angle is the ratio of the opposite side to the adjacent side (or sin/cos).
  • Cosecant (csc): The reciprocal of sine (1/sin).
  • Secant (sec): The reciprocal of cosine (1/cos).
  • Cotangent (cot): The reciprocal of tangent (1/tan or cos/sin).
Inverse Trigonometric Functions

Inverse trigonometric functions find the angle when given a trigonometric value:

  • Arcsin (sin-1): Returns the angle whose sine equals the given value.
  • Arccos (cos-1): Returns the angle whose cosine equals the given value.
  • Arctan (tan-1): Returns the angle whose tangent equals the given value.
Common Values to Remember

30° 1/2 √3/2 1/√3
45° √2/2 √2/2 1
60° √3/2 1/2 √3
90° 1 0 undefined
