Cosine definition
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

Tipps und häufige Fehler
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.
Annahmen und Einschränkungen
- Use the stated inputs and units.
- Results are estimates for planning and education.
- Check measurements and source data before making an important decision.
