Unformatted text preview: same sign. Thus, the minus sign in front of the last expression is not possible (since that would switch the signs of tan 1 2 and sin ), so we have: tan 1 2 = 1 cos sin (3.34) Multiplying the numerator and denominator in formula (3.34) by 1 + cos gives tan 1 2 = 1 cos sin 1 + cos 1 + cos = 1 cos 2 sin (1 + cos ) = sin 2 sin (1 + cos ) , so we also get: tan 1 2 = sin 1 + cos (3.35) Taking reciprocals in formulas (3.34) and (3.35) gives: cot 1 2 = sin 1 cos = 1 + cos sin (3.36)...
