♣ The graph of y = sin(Bx + C) will have a horizontal shift of?

---
sorry, said cot but it's tan $$y=\tan\left({3x-\frac{\pi}{2}}\right)$$♣ State the period and horizontal shift for the graph. (Find these values using the methods given in this definition http://goo.gl/GsVjUr )
period: π
horizontal shift: ???
I put the below answer and was told that it was wrong:$$-\frac{3}{2}$$

woops typed wrong

imqwerty · Answer

$$y=\cot \left( 3x-\frac{ \pi }{ 2 } \right)$$
$$y=\cot(Bx+C)$$
comparing we get->B=3
C=-pi/2

period =pi/B

horizontal shift=-C/B

substitute B and C to get answers

phi · Answer

it is shifted + pi/6
