Graph the trigonometric function using the amplitude,period,phase shift and vertical shift.
Vertical Asymptotes:x=pi/6 =pi n/2 where n is an integer
Amplitude is none
period is pi/2
phase shift is pi/6 to the right 
vertical shift is 0
 
        
        
        
12.38 in expanded form is write like:-
10 + 2 + .3 + .08 = 12.38
To write a number in expanded form just means to write the number in a layout and when you add it up it will become the number you needed to write in expanded form. 
So, 12.38 written in expanded form is:- 10 + 2 + .3 + 0.8
