Write the equation for the inverse of each function. Then graph the function and it inverse.
This is the original function y=tan x/2
This is what I did
y= tan x/2
x=tan y/2
2x=tan y
y= 2 arc-tan x
But I am confused on how to graph these functions as they have pi as the asymptote while on other tan function it is zero. Can anyone show me how to graph this function as I am confused?
I might sound really dumb when I say this but what I do not really understand is how -pi and pi are asymptotes according to the back of my book because I usually think of them being zero.It boggle the mind because when I look at my unit circle I see pi as coordinates (-1,0) then I put opposite/adjacent which is zero why is it an asymptote here? That x/2 only changes period right or maybe there is something I am overlooking.
I mean I understand the post you put above me and this is what I really meant to ask. No disrespect.
So what would that make -pi/2 and pi/2 as a domain what would you plug in the range. Would for -pi/2 would it be -2 and for pi/2 positive 2? Anyway I think I understand this now. And for x=zero y=zero I think I understand this now I was lost in darkness but now I see the light.
