Basic Math Help Please?
posted by jaret .
find the next two positive and negative angles coterminal with the quadrantal angle.
90 degrees.
I am really confused, what would the two positive and two least negative numbers be? i know it you add or subtract 360.

Assistance needed.

I think you would just add and subtract multiples of 360° to end up in the same postion (coterminal)
coterminal with 90° in the positive direction:
450° and 810°
in the negative direction:
270° and 630°
