You can put this solution on YOUR website! Graph: 
   
 In form: y=a*tan(bx+c)+d ----> a=1, b=1, c=3pi/2, d=0
 
 Period: T=pi/b=pi/1=pi
 Period is pi radians or 180 degrees
 
 Undefined Values:
 tan(x+3pi/2) = sin(x+3pi/2)/cos(x+3pi/2)
 
 ---> cos(x+3pi/2) = sin(x) = 0 --->  x = pi*n
 
 Undefined Values: -2pi, -pi, 0, pi, 2pi, etc...
 
 
 Phase Shift: -c/b = (3pi/2)/1 = -3pi/2
