What is COS also equal to?

In other words, the cosine of an angle in a right triangle equals the adjacent side divided by the hypotenuse: Also, cos A = sin B = b/c.

Is csc the opposite of sin?

The cosecant ( csc ⁡ ) (\csc) (csc)

The cosecant is the reciprocal of the sine. It is the ratio of the hypotenuse to the side opposite a given angle in a right triangle.

Trigonometric Functions: Sine, Cosine, Tangent, Cosecant, Secant, and Cotangent



What value is cos?

Commonly used angles

As can be seen from the figure, cosine has a value of 0 at 90° and a value of 1 at 0°. Sine follows the opposite pattern; this is because sine and cosine are cofunctions (described later).

What is cosecant formula?

In a right-angled triangle, cosecant is equal to the ratio of the hypotenuse and perpendicular. Since it is the reciprocal of sine, we write it as csc x = 1 / sin x.

What is csc in terms of sin and cos?

tan x = sin x cos x . 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 .

Is Arcsin the same as cosecant?

As nouns the difference between arcsine and cosecant

is that arcsine is (trigonometry) any of several single-valued or multivalued functions that are inverses of the sine function symbol: arcsin, sin-1 while cosecant is (trigonometry) in a right triangle, the reciprocal of the sine of an angle symbols: cosec, csc.

What is arcsec equivalent to?

Arcsec(cos u) = π when u = (2k+1)π If u is not a multiple of π, cos u will be less than 1 and greater than −1. The Arcsec function is not defined for such values, and therefore. Arcsec(cos u) does not exist when u is not a multiple of π

Is Arctan and cot the same?

arctan(x)

It turns out that arctan and cot are really separate things: cot(x) = 1/tan(x) , so cotangent is basically the reciprocal of a tangent, or, in other words, the multiplicative inverse. arctan(x) is the angle whose tangent is x.

Why is cosecant the reciprocal of sine?

Since sine function is the ratio of the lengths of the opposite side to the angle in consideration and hypotenuse in a right-angled triangle, the reciprocal of sine is the ratio of the hypotenuse and the opposite side of a right-angled triangle which is the formula for the cosecant function.

What is cos in math?

Cos function (or cosine function) in a triangle is the ratio of the adjacent side to that of the hypotenuse. The cosine function is one of the three main primary trigonometric functions and it is itself the complement of sine(co+sine).

What is cot equal to?

In trigonometry, cot or cotangent is one of six trigonometric ratios. In a right-angled triangle, cot of an angle is equal to the ratio of adjacent side and opposite side of angle. Cot x is also equal to the reciprocal of tan x.

What is arcsin also called?

The inverse sine function (also called arcsine) is the inverse of sine function. Since sine of an angle (sine function) is equal to ratio of opposite side and hypotenuse, thus sine inverse of same ratio will give the measure of the angle.

Is reciprocal the same as inverse?

“Inverse” and “reciprocal” are terms often used in mathematics. “Inverse” means “opposite.” “Reciprocal” means “equality,” and it is also called the multiplicative inverse.
