CHECK PLEASE Tan BEHAviour IN TRANSFORMATION

  1. Sep 13, 2005 #1
    HOw does [tex] y-3=-\tan (-2x+\pi) [/tex] differ from [tex] y=tan(x) [/tex]

    [tex] y=-\tan [-2 (x+ \frac {\pi} {2} )] +3 [/tex] rearranged

    It differs because it has a

    Horizontal compression by a factor of 1/2
    it is reflected in the x and y axis
    there is a horizontal translation [tex] \frac {\pi} {2} [/tex] units to the left
    and a vertical displacement 3 uinits up.

    Can someone please tell me if I made any mistakes?

    hallosivy, shouldnt that be -2(x-pi/2) instead of plus ?

    Yep, sorry, didn't look close enough.
