The secant function is not defined for odd multipls of 90o.
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).
90 degrees 90 degrees
It is: 90-83.5 = 6.5 degrees
rotate it 90 degrees
obtuse: greater than 90 degrees right: 90 degrees acute: less than 90 degrees
secant of (A) = cosecant of (90- A) 'A' here is 80 degrees.
cosecant = 1/sine csc 90 deg = 1/(sin 90 deg) = 1/1 = 1
Yes. Both are defined on all points other than odd multiples of 90 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).
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.

90 degreesThere are 90 degrees in a right angle.There are 90 degrees in a right angle
In degrees, the distance from (zero) to (90 degrees) is 90 degrees.
Sine and cosine are cofunctions, which means that their angles are complementary. Consequently, sin (90° - x) = cos x. Secant is the reciprocal of cosine so that sec x = 1/(cos x). Knowing these properties of trigonometric functions, among others, will really help you in other advance math courses.
