Answer by scott8148(6628) (Show Source):
You can put this solution on YOUR website! "All Students Take Calculus" ... this "memory crutch" tells you which trig functions (sin, cos, tan) are >=0 in each quadrant
all in the first, sin in the second, tan in the third, and cos in the fourth
so A is in the fourth quadrant
