Question: secx is the same as?
Answer: The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x . = tan 5π 4 . ... The period of sec x is precisely the same as that of cos x, which means that the period of sec x is 2π.
