  The 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 ...

  cos is the x-coordinate of the point. sin is the y-coordinate of the point. The picture of the unit circle and these coordinates looks like this: 1. Some trigonometric identities follow immediately from this de nition, in particular, since the unit circle is all the points in plane with xand ycoordinates

  Now, let us sketch the derivative of cosx.First, plot the graph of cosx over the closed interval [0;2… Again, we need to find the critical points of cosx.There are three critical points on this interval: at x = 0, x = …, and x = 2….So the graph of the derivative of cosx touches the x-axis on this interval at three points: (0;0), (…;0), and (2…;0).). Now we look for the inflection ...

  Since sin(4)(x) = sin(x), this pattern will repeat. Next we need to evaluate the function and its derivatives at 0: sin(0) = 0 sin (0) = 1 sin (0) = 0 sin (0) = −1 sin(4)(0) = 0. Again, the pattern repeats. Taylor’s formula now tells us that: sin(x) = 0 + 1x + 0x2 + 4 − 3! 1 x 3 + 0x + ··· x3 5 7 = x − 3! + 5! − 7! + ··· Notice ...

  To displace any function f(x) to the right, just change its argument from x to x-x 0, where x 0 is a positive number. If we let x 0 = v t, where v is positive and t is time, then the displacement increases with increasing time. So f(x-vt) represents a rightward, or forward, propagating wave. Similarly, f(x+vt) represents a leftward, or backward,
