I might have learned on this day that the signs of Sin(x), Cos(x), and Tan(x) in quadrants I, II, III, and IV, can be given by ASTC (All Students Take Calculus). That is "All" are positive, only "Sine" is positive, only "Tangent" is positive, and finally only "Cosine" is positive, in quadrants I, II, III, and IV, respectively.
