The function sec(x) is the secant function. It is related to the other functions by the expression 1/cos(x). It is not the inverse cosine or arccosine, it is one over the cosine function. Ex. cos(pi/4)= sqrt(2)/2 therefore secant is sec(pi/4)= 1/sqrt(2)/2 or 2/sqrt(2).

Secant(3pi/4) = 1/cos(3pi/4) = 1/[-1/sqrt(2)] = -sqrt(2)

2*Pi
2*pi radians.
It is 2*sqrt(3)/3.
Since secant theta is the same as 1 / cosine theta, the answer is any values for which cosine theta is zero, for example, pi/2.
The function sec(x) is the secant function. It is related to the other functions by the expression 1/cos(x). It is not the inverse cosine or arccosine, it is one over the cosine function. Ex. cos(pi/4)= sqrt(2)/2 therefore secant is sec(pi/4)= 1/sqrt(2)/2 or 2/sqrt(2).
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).

tan^2(x) + 1 = sec^2(x) for x not equal to odd multiples of pi/2 radians (90 deg).
The period of the tangent function is PI. The period of y= tan(2x) is PI over the coefficient of x = PI/2
It is 360 degrees.
