Cosine.
I find it convenient to express other trigonometric functions in terms of sine and cosine - that tends to simplify things. The secant function is even because it is the reciprocal of the cosine function, which is even. The tangent function is the sine divided by the cosine - an odd function divided by an even function. Therefore it is odd. The cosecant is the reciprocal of an odd function, so it is naturally also an odd function.
a secant is a line containing a chord. A secant is a line that intersects the circle twice(or passes through a circle)
Substitute secant(x)=1/cos(x) into your equation, and you should be able to solve from there.
I am almost positive that it isn't because a secant is an extended chord so it goes out of circle. So no it is not.

Reciprocal of Cosine is Secant
It is the reciprocal of the sine ratio.
it would be secant, 1/cosine
You can calculate the cosine and then its reciprocal.
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).
The reciprocal of cosine is secant (short form: sec), which is the hypotenuse length divided by the adjacent length.
The secant of an angle is the reciprocal of the cosine of the angle. So the secant is not defined whenever the cosine is zero That is, whenever the angle is a multiple of 180 degrees (or pi radians).
Inverse of Cosine is 'ArcCos' or Cos^(-1) The reciprocal of Cosine is !/ Cosine = Secant.
The secant of an angle is defined as the reciprocal of the cosine of that angle. At 270 degrees, the cosine is 0, so the secant, which is 1/cos(270°), is undefined. Therefore, the secant of 270 degrees does not have a defined value.
The answer is cos A . cos A = 1/ (sec A)
1/cos(x)=sec(x). sec is short for secant.
cosecant = 1/sine secant = 1/cosine cotangent = 1/tangent
