Key Trigonometric Ratios
- Sine (sin) = opposite side / hypotenuse
- Cosine (cos) = adjacent side / hypotenuse
- Tangent (tan) = opposite side / adjacent side
Applications
- Trigonometric ratios are used in various fields such as engineering, physics, and architecture.
- Essential for solving problems related to angles and distances in triangles.
Importance of Unit Circle
- Understanding trigonometric ratios is enhanced by familiarizing with the unit circle.
- Provides the values of sine, cosine, and tangent for key angles (0°, 30°, 45°, 60°, 90°).
Relationships Between Ratios
- Cotangent (cot) is the reciprocal of tangent.
- Secant (sec) is the reciprocal of cosine.
- Cosecant (csc) is the reciprocal of sine.
Graphs of Trigonometric Functions
- Understanding the graphical representation of sine, cosine, and tangent functions can aid in visualizing their behaviour over different intervals.
