The two trigonometric functions defined for all real numbers are the sine and cosine functions.

Trigonometry functions are functions used to represents the ratio of the sides of a right-angled triangle. The SOH CAH TOA theorem is used to solve for sides and angles of the right triangle.

Examples of trigonometric functions that we have include:

  • Sine function
  • Cos function
  • Tan function

Out of the examples of the trigonometry functions listed, only sine and cosine are the two trigonometric functions defined for all real numbers since the domain of both functions exists for all real numbers except tangent and other trigonometric functions that are periodic functions.
