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
81 is 45% of 180, all you do is divide 81 by .45 and boom there you go
1116 is the perimeter it has. The formula for perimeter is 2l+2w=p
so when you plug the numbers in you get 2(309)+2(249)=1116. So it does not have a perimeter of 1500 cm.
