Cosine definition

cos(θ) = adjacent / hypotenuse

In a right triangle, the cosine of an angle is the ratio of the length of the adjacent side to the length of the hypotenuse.

Example:

Input: θ = 60°, adjacent = 1, hypotenuse = 2

Calculation: cos(60°) = 1/2

Result: 0.5

Consejos y errores comunes

Tips

  • Remember that cosine is an even function: cos(-θ) = cos(θ).
  • Use the unit circle to visualize cosine values for common angles.
  • For angles in radians, use the formula directly without conversion.
  • Check if your calculator is in degree or radian mode.

Common Mistakes to Avoid

  • Forgetting to convert degrees to radians when using a calculator in radian mode.
  • Confusing cosine with sine or tangent.
  • Assuming cosine values can exceed 1 or be less than -1.

Supuestos y limitaciones

  • Use the stated inputs and units.
  • Results are estimates for planning and education.
  • Check measurements and source data before making an important decision.
