Solve sin (α /7) =0 .
Solution
By Using a unit circle it isn't too difficult to see that the solutions to this equation are,
α /7 = 0 + 2 ? n ⇒ α = 14 ? n
α = 7 ? +14 ? n n= 0, ±1, ±2,............
α /7 = ? + 2 ? n
This next example has significant point that needs to be understood when solving some trig equations.
