A trigonometric function is a mathematical function that relates the angles of a triangle to the lengths of its sides. The most commonly known trigonometric functions are sine, cosine, and tangent.
No, not all trigonometric functions are polynomial functions. Only the sine and cosine functions can be expressed as infinite polynomial series.
A polynomial function is a mathematical expression made up of variables, coefficients, and exponents, while a trigonometric function involves the use of angles and ratios to represent a relationship between sides of a triangle.
Trigonometric functions are used in various fields of science, such as physics, engineering, and astronomy. They are used to model and analyze periodic phenomena, such as waves and oscillations.
Yes, trigonometric functions can be used to solve real-world problems that involve angles and triangles. They are commonly used in navigation, surveying, and architecture, among other applications.
