It is the reciprocal of the sine ratio.
No, the co-secant (csc) of an angle cannot be less than 1 or greater than -1. This is because the co-secant is defined as the reciprocal of the sine function (csc(θ) = 1/sin(θ)). Since the sine of an angle ranges from -1 to 1, the co-secant will either be greater than or equal to 1 when sine is positive or less than or equal to -1 when sine is negative.
The answer depends on whether the angle is 20 degrees or 20 radians.
2/sqrt(3) or (2sqrt(3))/3
It is the same period as cosine function which is 2 pi because sec x = 1/cos x
yes
That is the correct spelling of the geometric term "secant."
