# Thread: Need help with a chart !!!

1. ## Need help with a chart !!!

For the following equations i need to find :

vert trans
horiz trans
period
asympt.
domain
range
rise or fall

a) y = tan 2x

b) y = 3 tan(x-pi/3)

c) y+2 = tan(x + pi/6)

d) -1/4(y-2) = tan(3x)

e) -1/2(y+1) = tan(x)

thank you for the help

Start by rearranging each of them so that y is the subject. Then they should all be of the form \displaystyle \displaystyle \begin{align*} y = a\tan{\left(bx - c\right)} + d \end{align*}, where \displaystyle \displaystyle \begin{align*} a \end{align*} is the dilation factor, \displaystyle \displaystyle \begin{align*} c \end{align*} is the horizontal translation, \displaystyle \displaystyle \begin{align*} d \end{align*} is the vertical translation, and the period is \displaystyle \displaystyle \begin{align*} \frac{\pi}{b} \end{align*}.

You could always try one yourself and we can guide you if you make a mistake...

a) 1/2 y -1 = sinx + 25 degrees
