WebMay 20, 2009 · This could have a physical meaning in some circumstances. Also, when doing trigonometric calculations, you should take this fact into consideration. For example: sin (a)*cos (a) = (1/2)*sin (2a) For a>180 you will get the sin of an angle greater than 360. By the way, have a look here. Share. Webthat the bounds on cosx are ¡1 • cosx • 1. So, we see that if the secant of x is positive, then it can be no smaller than 1, and if it is negative, it can be no larger than ¡1. Thus the range of secx is made up of two intervals: secx ‚ 1 or secx • ¡1: The period of secx is precisely the same as that of cosx, which means that the ...
