You can put this solution on YOUR website! how to graph: Here is the equation:
 y = cot (1/2 x)
 **
 Standard form of equation for cos function:y=Acot(Bx-C), Period=π/B, Phase shift=C/B, A=multiplier which stretches the curve vertically.
 ..
 For given cot function:
 A=1, so there is no stretching
 Phase shift: none
 B=1/2
 Period: π/B=π/(1/2)=2π
 ..
 Graphing for one period:
 On an (x,y) coordinate system, draw vertical asymptotes at x=0, and x=2π
 On the x-axis, make tick marks at π/2, π, and 3π/2.
 At these x-values, y=1, 0 and  -1 respectively
 With the 2 vertical asymptotes and 3 points, you should be able to draw the graph of
 y=cot(1/2 x)
