What does ASTC stand for and mean?
@smartalexmathematics
@smartalexmathematics 10 ай бұрын
ASTC is an acronym used to help memorise the signs of trig functions in different quadrants. ASTC stands for All Stations To Central A corresponds to Quadrant 1 where All functions (Sin, Cos and Tan) are positive. S corresponds to Quadrant 2 where only Sin function is positive. T corresponds to Quadrant 3 where only Tan function is positive. C corresponds to Quadrant 4 where only Cos function is positive. Hope that helps.
