In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.
The basic trigonometric functions are sine, cosine, tangent, cotangent, secant and cosecant. Also, read trigonometric identities here. Table of Contents: Basic Trigonometric Functions. Sine. Cosine. Tangent. Cotangent, Secant, Cosecant. Formulas. Identities. Table. Graphs. Examples.
Identify the graphs and periods of the trigonometric functions. Describe the shift of a sine or cosine graph from the equation of the function. Trigonometric functions are used to model many phenomena, including sound waves, vibrations of strings, alternating electrical current, and the motion of pendulums.
Trigonometric functions are functions related to an angle. There are six trigonometric functions: sine, cosine, tangent and their reciprocals cosecant, secant, and cotangent, respectively. Sine, cosine, and tangent are the most widely used trigonometric functions.
The six basic trigonometric functions are sine function, cosine function, secant function, co-secant function, tangent function, and co-tangent function. The trigonometric functions and identities are the ratio of sides of a right-angled triangle.

Jun 17, 2024 · There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). These six trigonometric functions in relation to a right triangle are displayed in the figure.
Basic Trigonometric Functions. The trigonometric functions relate the angles in a right triangle to the ratios of the sides. Given the following triangle: \hspace {4cm} the basic trigonometric functions are defined for 0 < \theta < \frac {\pi} {2} 0 < θ < 2π as.
