Main Question or Discussion Point
Question, in order to produce a 270 degree geometric rotation of the complex number (a + bi), would this be correct:
(a + bi) * (-i)
It seems logical since a 90 degree rotation results from (a + bi) * (i)
Next question. What would be the equations for rotation of (a + bi) by 45 degrees, 135 degrees, 225 degrees ?
Thanks for help.
