Answer 2

Trigonometric functions are real-valued functions.

1. They are also known as circular functions, angle functions and goniometric functions.
2. They are related to a right-angled triangle as the ratio of two sides.
3. Common examples of trigonometric functions are

• Sine (sin α) - It is the ratio of opposite side of an angle, other than 90° to the hypotenuse.
• Cosine (cos α) - It is the ratio of adjacent side of an angle, other than 90° to the hypotenuse.
• Tangent (tan α) - It is the ratio of opposite side of an angle, other than 90° to the adjacent side.
• Cosecant (cosec α) - It is the ratio of hypotenuse of an angle, other than 90° to the opposite side.
• Secant (sec α) - It is the ratio of hypotenuse of an angle, other than 90° to the adjacent side.
• Cotangent (cot α) - It is the ratio of adjacent side of an angle, other than 90° to the opposite side.
