secant of (A) = cosecant of (90- A) 'A' here is 80 degrees.
20 degrees
40, 100 and 83, 143.
yes
Yes. Both are defined on all points other than odd multiples of 90 degrees.
The secant function is not defined for odd multipls of 90o.
secant of (A) = cosecant of (90- A) 'A' here is 80 degrees.
It is 360 degrees.
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).
20 degrees
40, 100 and 83, 143.
secant(2) =1/cos(2) for which you can use a calculator. However, you need to know whether the angle is measured in degrees or radians.
The answer depends on whether the angle is 20 degrees or 20 radians.
yes
Yes. Both are defined on all points other than odd multiples of 90 degrees.
That is the correct spelling of the geometric term "secant."
