What is sec csc cot called?

Learn how cosecant, secant, and cotangent are the reciprocals of the basic trig ratios: sine, cosine, and tangent.

What is csc identity?

Cosecant Function: csc(θ) = Hypotenuse / Opposite. Secant Function: sec(θ) = Hypotenuse / Adjacent.

What are the six trig functions?

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).

What is cosecant formula?

The cosecant formula is given as follows: cosec A = hypotenuse / opposite side = AB / BC = c / a. We know that, sin A = opposite side / hypotenuse. Cosecant is the reciprocal of sine.

What is sec cosec and cot?

Secant (sec) is the reciprocal of cosine (cos) Cosecant (cosec) is the reciprocal of sin. Cotangent (cot) is the reciprocal of tan.

What is cotangent used for?

Cotangent is used the same way the sine, cosine, and tangent functions are used. You can use them based on a right triangle, using the opposite and adjacent sides of the triangle, or you can use it based on the unit circle, which shows the angles in radians.

What is cot identity?

The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x . The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .

What is a sec math?

The secant function is a periodic function in trigonometry. The secant function or sec function can be defined as the ratio of the length of the hypotenuse to that of the length of the base in a right-angled triangle. It is the reciprocal of cosine function and hence, is also written as sec x = 1 / cos x.

What is cot in trigonometry?

The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x .

What is SEC SEC cosec and cot X?

Sec, Cosec and Cot. Secant, cosecant and cotangent, almost always written as sec, cosec and cot are trigonometric functions like sin, cos and tan. sec x = 1. cos x. cosec x = 1. sin x. cot x = 1 = cos x. tan x sin x. Note, sec x is not the same as cos -1 x (sometimes written as arccos x).

What do the points labelled 1 SEC SEC and CSC represent?

The points labelled 1, Sec (θ), Csc (θ) represent the length of the line segment from the origin to that point. Sin (θ), Tan (θ), and 1 are the heights to the line starting from the x -axis, while Cos (θ), 1, and Cot (θ) are lengths along the x -axis starting from the origin.

What is the domain of the cotx cot ⁡ X function?

From the graph, it is clear that the multiples of π π do not lie in the domain of this function. Thus, the domain of the cotx cot ⁡ x function is R −{nπ} R − { n π }.

Is sec x the same as cos-1 x?

Note, sec x is not the same as cos -1 x (sometimes written as arccos x). Remember, you cannot divide by zero and so these definitions are only valid when the denominators are not zero.
