Explanation Formula used: The known trigonometric identity is that sin A − sin B = 2 cos ( A + B 2 ) sin ( A − B 2 ) . Calculation: The given expression is sin 7 t − sin 6 t . Apply the above formula by substituting A = 7 t and B = 6 t as follows. sin 7 t − sin 6 t = 2 cos ( 7 t + 6 t 2 ) sin ( 7 t − 6
