The value of tan A is not clear from the question.However, sin A = sqrt[tan^2 A /(tan^2 A + 1)]
tan(135) = -tan(180-135) = -tan(45) = -1
tan(22.5)=0.414213562
Tan 42 degrees = 0.9004
tan(61°) = 1.80405 (rounded)
= tan (48.323 deg) = 1.1232
tan(-x) = -tan(x)
tan 2 pi = tan 360º = 0
tan(135 degrees) = negative 1.
tan(-60 degrees) = - sqrt(3)
