Right Triangle Definitions Of Cosecant Secant And Cotangent Math Properties of trigonometric functions. the properties of the 6 trigonometric functions: sin (x), cos (x), tan (x), cot (x), sec (x) and csc (x) are discussed. these include the graph, domain, range, asymptotes (if any), symmetry, x and y intercepts and maximum and minimum points. With the exception of the sine (which was adopted from indian mathematics), the other five modern trigonometric functions were discovered by persian and arab mathematicians, including the cosine, tangent, cotangent, secant and cosecant. [32] al khwārizmī (c. 780–850) produced tables of sines, cosines and tangents.
Cotangent Definition Formulas Facts Britannica Pythagoras theorem. for the next trigonometric identities we start with pythagoras' theorem: the pythagorean theorem says that, in a right triangle, the square of a plus the square of b is equal to the square of c: a 2 b 2 = c 2. dividing through by c2 gives. a2 c2 b2 c2 = c2 c2. this can be simplified to: (a c)2 (b c)2 = 1. An odd function is a function in which f(x)=f( x). it has symmetry about the origin. an even function is a function in which f(x)=f( x) meaning that reflecting the graph across the y axis will yield the same graph. of the 6 trigonometric functions, sine, tangent, cosecant, and cotangent are odd functions. cosine and secant are even functions. For example see the graph of the sin function, often called a sine wave, above. for more see graph of the sine function; graph of the cosine function; graph of the tangent function; pure audio tones and radio waves are sine waves in their respective medium. derivatives of the trig functions. each of the functions can be differentiated in calculus. Note the full names of these functions: sine and cosine, secant and cosecant, tangent and cotangent. these pairs are referred to as cofunctions. the angles \(a\) and \(90^{\circ} a\) are complementary. in other words, the cofunctions of any pair of complementary angles are equal.

The first one is a reciprocal: csc θ = 1 sin θ. \displaystyle \csc {\ }\theta=\frac {1} { { \sin {\ }\theta}} csc θ = sin θ1 . . the second one involves finding an angle whose sine is θ. so on your calculator, don't use your sin 1 button to find csc θ. we will meet the idea of sin 1θ in the next section, values of trigonometric. The secant, cotangent, and cosecant are all reciprocals of other functions. the secant is the reciprocal of the cosine function, the cotangent is the reciprocal of the tangent function, and the cosecant is the reciprocal of the sine function. the six trigonometric functions can be found from a point on the unit circle.
