1 . Given the coordinate grid below, write in what trig functions are in each quadrant. They may be in
more than one quadrant each.

Questions 2-5. Given one trig function in Quadrant 1, find the remaining 5 trig function values. No
calculator. Reduce answers. No radicals in the denominator of answers!
