In trig how is the value of r interpreted geometrically in the definitions of the sine cosine secant and cosecant?
In trigonometry, the value of R is the radius of the circle, and is usually normalized to a value of 1. If the circle is at the X-Y origin, and theta is the angle between the radius line R, and X and Y are the X and Y coordinates of the point on the circle at the radius line, then... sine(theta) = Y / R cosine(theta) = X / R secant(theta) = 1 / cosine(theta) = R / X cosecant(theta) = 1 / sine(theta) = R / Y
What else can I help you with?
How do you find the cosine and the sine?
Sine= Opposite/ Hypotenuse Cosine= Adjacent/ Hypotenuse
Is the cosine adjacent to the hypotenuse?
Nearly! The cosine is the adjacent side (ie not the opposite side) divided by the hypotenuse.
If the tangent of an angle is 2 what is the cosine?
The cosine is ±1/sqrt(5) = ±0.4472 (approx).
What is the cosine of pi?
0.99847149863
How do you find cosine squared at 30 degrees?
cos(30) = sqrt(3)/2 so cosine squared is 3/4.
What does csc stand for on a calulator?
Cosecant, or the inverse of the cosine.
What are the trigonometric functions?
sine, cosine, tangent, cosecant, secant and cotangent.
What are circular functions?
Sine, Cosine, Tangent, Cotangent, secant and cosecant
What are the six trigonometry function?
sine, cosine, tangent, cosecant, secant, cotangent.
What is the six trigo function of acute angle?
Sine, Cosine, Tangent, Cosecant, Secant, Cotangent.
What is Secany squared times cotangent times cosine?
Assuming that "secany" is meant to be secant, the answer is cosecant.
What are functions in trigonometry?
The basic functions of trigonometry are: sine cosine tangent secant cosecant cotangent
What are the six trigonometric functions of special angles?
sine, cosine, tangent, cosecant, secant and cotangent.
Is the inverse function of secant is the cosecant function?
No. The inverse of the secant is called the arc-secant. The relation between the secant and the cosecant is similar to the relation between the sine and the cosine - they are somehow related, but they are not inverse functions. The secant is the reciprocal of the cosine (sec x = 1 / cos x). The cosecant is the reciprocal of the sine (cos x = 1 / sin x).
Why dont you have buttons for cotangent secant cosecant?
You don't have buttons for cotangent, secant, and cosecant because you don't need them. Just invert. Cotangent is 1 over tangent, secant is 1 over sine, and cosecant is 1 over cosine.
What is the Sine reciprocal?
Sine Its reciprocal is Cosecant Algebraically Sin ; Reciprocal is '1/ Sin' known as 'Cosecant(Csc)'. Similarly Cos(Cosine) ; 1/ Cos (Secant(Sec)) Tan(Tangent) ; 1/ Tan ( Cotangent(Cot)).
What is trigonometry of reciprocal relation?
cosecant = 1/sine secant = 1/cosine cotangent = 1/tangent
