Circular Function (Noun)
Meaning
Function of an angle expressed as a ratio of the length of the sides of right-angled triangle containing the angle.
Classification
Nouns denoting relations between people or things or ideas.
Examples
- The sine, cosine, and tangent are examples of circular functions used to describe the relationships between the angles and side lengths of a right triangle.
- Circular functions are essential in trigonometry, as they allow us to calculate unknown side lengths and angles in triangles.
- The circular function of an angle in a right triangle is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse.
- In calculus, circular functions are used to model periodic phenomena, such as sound waves and light waves.
- The circular functions of sine, cosine, and tangent are used to describe the relationships between the angles and side lengths of a right triangle, and are essential in many fields, including physics and engineering.
