Study Notes
Trigonometric Concepts
- Cosine A is abbreviated as cos A.
- A trigonometric identity is an equation that is true for all values of the variables.
- In a right triangle ABC, right-angled at B, cotangent A is the ratio of the adjacent side to the opposite side.
- The reciprocal of sin A is cosecant A.
- A trigonometric identity represents a universal truth that is true for all angles and triangles.
- Secant A is abbreviated as sec A.
- Cot θ equals 1/tan θ.
- Tangent A is abbreviated as tan A.
- Cosecant A is the reciprocal of sin A, or 1/sin A.
- The statement "A t-ratio only depends upon the angle ‘θ’ and stays the same for same angle of different sized right triangles" refers to the property of trigonometric ratios being independent of the size of the triangle.
