ms.mcmaster.caThe frequency (f) of a sine or cosine function is typically expressed in terms of the number of cycles per unit time. For example, in the above gure the frequency of each function is 2 cycles per unit time. The period (T) of a sine or cosine function …
Tangent, Cotangent, Secant, and Cosecant
math.dartmouth.eduThe range of cscx is the same as that of secx, for the same reasons (except that now we are dealing with the multiplicative inverse of sine of x, not cosine of x).Therefore the range of cscx is cscx ‚ 1 or cscx • ¡1: The period of cscx is the same as that of sinx, which is 2….Since sinx is an odd function, cscx is also an odd function. Finally, at all of the points where cscx is ...
