a = all trig functions are positive in this quadrant

s = only sine is positive in this quadrant

t= only sine is positive in this quadrant

c= only sine is positive in this quadrant

so if sine and cos are negative they must be in between 180 and 270.

u cn also use the sentence 'all silver tea cups' (ASTC) to remembr the quadrant thing...it actually helpd me in nov 09 add maths
