i get that it turns anticlockwise, but i dont get it when they say by pi/4?

Note how the argument increases by pi/4 each time. The argument is the non-reflex angle the complex number makes with the positive real axis, so if it increases, the number is being rotated.

oh ok... thanks guys :)

i'm sorry but...
If tx = y and ty = x, prove that tx+y ,= 0 (tx and ty are the xth and yth terms of an
arithmetic sequence).
thank you

^Can you rewrite it more clearly? Is it something like this?:

Suppose that is an arithmetic sequence. Suppose there are some integers such that and . Show that (or is it ?)

Also: Should we assume that ?
