Why are they not the same?!!!!

[TrueTears]

Just a question on a similar note. The dotted line that you normally add for inequalities gets rotated around too yeah?

So for

You're gonna have a dotted line at rather than the usual ?

Correct

Sorry to hi-jack your thread TT.

Anyway, using the method of splitting up the arguments, for NE2000's , why does my diagram differ from his description?



Sorry still unsure about this. I also tried using transformations for another similar question and I don't really get it. GG.

i.e. You rotate every point on the graph of 90 degrees clockwise about the origin.

The dotted line at goes to .

The dotted line at goes to .

Also, for this thead's question, , using that substitution method:





Isn't it translate 2 units to the right then rotate clockwise by 90 degree? I'm lost as to why kamil and TT say it's translates to the left. Or maybe it's getting a bit late.

[dekoyl]

Bump.

[NE2000]

Yeah it's translate to the left. Let's forget the rotation for now and look at z = z' - 2. That tells you that z is z' minus 2. So every z' value moves 2 to the left to produce z.

Hold on, isn't it , not ?

The original equation is
