The trigonometric identity sin A = cot B must be checked at specific standard angles by evaluating both sides. Since sin A ranges only between -1 and 1 while cot B is unbounded except at specific values, examining boundary/special angle cases (0 and pi/2) shows that A = 0 and B = pi/2 make both sides equal to zero.
Evaluate sin A = cot B at the given candidate value pairs. At A = 0, sin A = sin 0 = 0. At B...
