Reciprocal of Cosine is Secant
1/cos(x)=sec(x). sec is short for secant.
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).
Cosine of -90 is 0.
The reciprocal of -3.4 is -0.294
Reciprocal of Cosine is Secant
Cosine.
A reciprocal trigonometric function is the ratio of the reciprocal of a trigonometric function to either the sine, cosine, or tangent function. The reciprocal of the sine function is the cosecant function, the reciprocal of the cosine function is the secant function, and the reciprocal of the tangent function is the cotangent function. These functions are useful in solving trigonometric equations and graphing trigonometric functions.
In a right angle triangle it is: cosine ratio = adjacent/hypotenuse
You can calculate the cosine and then its reciprocal.
It is the cosine ratio.
The reciprocal of cosine is secant (short form: sec), which is the hypotenuse length divided by the adjacent length.
If the numerator is 0 AND the denominator is not 0, then the ratio is 0. And cosine of 0 is 1.
The ratio of sine and cosine.
By doing it
In a specific angle for a right triangle the cosine ratio is the ratio between the lengths of the adjacent side (side touching the angle) and the hypotenuse (longest side).
A cosine is a trigonometric ratio and is not capable of liking or disliking anything!
