If 1 – tan θ tan 4θ ≠ 0, you can peacefully divide by this expression. ... 1 – tan (nπ/3) tan (nπ/12) ≠ 0 .... Solution: Do not get confused by π cos θ or π sin θ in the arguments as they are .... Then each of (a – b)2, (b – c)2 and (c –a)2 must be zero ⇒ a = b, b = c, c = a. ... Example 9: Solve the following equations for x and y.
