Conventionally, an abbreviation of each trigonometric function's name is used as its symbol in formulas. Today, the most common versions of these abbreviations are "sin" for sine, "cos" for cosine, "tan" or "tg" for tangent, "sec" for secant, "csc" or "cosec" for cosecant, and "cot" or "ctg" for cotangent. … See more 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. They are widely … See more In geometric applications, the argument of a trigonometric function is generally the measure of an angle. For this purpose, any angular unit is convenient. One common unit is degrees, in which a right angle is 90° and a complete turn is 360° (particularly in See more The algebraic expressions for the most important angles are as follows: Writing the … See more Many identities interrelate the trigonometric functions. This section contains the most basic ones; for more identities, see List of trigonometric identities. These identities may be proved … See more If the acute angle θ is given, then any right triangles that have an angle of θ are similar to each other. This means that the ratio of any two side lengths depends only on θ. Thus these six … See more The six trigonometric functions can be defined as coordinate values of points on the Euclidean plane that are related to the unit circle, which is the circle of radius one centered at the origin O of this coordinate system. While right-angled triangle definitions allow for … See more The modern trend in mathematics is to build geometry from calculus rather than the converse. Therefore, except at a very elementary level, trigonometric functions are defined using … See more WebFor every trigonometry function such as csc, there is an inverse function that works in reverse. These inverse functions have the same name but with 'arc' in front. So the inverse of csc is arccsc etc. When we see "arccsc …

Trigonometry Definition, Formulas, Ratios, & Identities
WebThe Pythagorean Identities are based on the properties of a right triangle. cos2θ + sin2θ = 1. 1 + cot2θ = csc2θ. 1 + tan2θ = sec2θ. The even-odd identities relate the value of a trigonometric function at a given angle to the value of the function at the opposite angle. tan(− θ) = − tanθ. cot(− θ) = − cotθ. WebWhat is Csc Sec Cot in Trigonometry? Csc sec cot are trigonometric functions named as, cosecant secant and cotangent, respectively. Csc sec cot are the reciprocal functions of sin cos tan, respectively. What are Csc … WebDo you mean the "Reciprocal functions" like secant and cosecant.
