WebThe 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 … WebWe define cos x = a and sin x = b Since ΔOMP is a right triangle, we have OM2 + MP2 = OP2ora2 + b2 = 1 Thus, for every point on the unit circle we have a2 + b2 = 1orcos2x + sin2x = 1 Since one complete revolution …
