of the sine. It is the reciprocal or multiplicative inverse of the sine, that is, csc θ · sin θ = 1.

What is the equivalent ratio for cosecant?

Allied to these are the three reciprocal ratios, cosecant, secant and cotangent: cosecθ=hypotenuseopposite,secθ=hypotenuseadjacent,cotθ=adjacentopposite. cosecθ=1sinθ,secθ=1cosθ,cotθ=1tanθ.

Is cosecant the inverse of sine?

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.

What is csc math?

In a right angled triangle, the cosecant of an angle is: The length of the hypotenuse divided by the length of the side opposite the angle. The abbreviation is csc.

How do you write cosecant?

Cosecant is one of the main six trigonometric functions and is abbreviated as csc x or cosec x, where x is the angle. 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.

Secant (sec), cosecant (csc) and cotangent (cot) example | Trigonometry | Khan Academy

Is cosecant the inverse of cosine?

Given a triangle rectangle, we define the cosecant, the secant and the cotangent of an angle as the inverse ratios of the sine, the cosine and the tangent, respectively.

What is the reciprocal of cosecant?

The reciprocal of the cosecant function is the sine function itself. The product of the reciprocal of sine and the sine function is always equal to 1. Reciprocal of sine is written as cosec x = 1/sin x.

What is csc in SOH CAH TOA?

For the triangle in the preceding figure: The other three trig functions are reciprocals of these: Cosecant (csc) is the reciprocal of sine, secant (sec) is the reciprocal of cosine, and cotangent (cot) is the reciprocal of tangent.

How do you find COS 180 without a calculator?

The value of cos 180 degrees can be calculated by constructing an angle of 180° with the x-axis, and then finding the coordinates of the corresponding point (-1, 0) on the unit circle. The value of cos 180° is equal to the x-coordinate (-1). ∴ cos 180° = -1.

How do you find the cosecant of a graph?

How do you find the csc on a graph?

Drawing the cosecant curve by using the sine as a guide. The cosecant goes down to the top of the sine curve and up to the bottom of the sine curve. After using the asymptotes and reciprocal as guides to sketch the cosecant curve, you can erase those extra lines, leaving just y = csc x.

What is reciprocal ratio?

(Math.) the ratio between the reciprocals of two quantities; as, the reciprocal ratio of 4 to 9 is that of ¼ to. See also: Reciprocal. Webster's Revised Unabridged Dictionary, published 1913 by G.
