WebSep 27, 2024 · My solution: sinθ + cosθ = √2sin2θ sinθ + cosθ = √2 × 2sinθcosθ sinθ + cosθ = 2√sinθcosθ sinθ − 2√sinθcosθ + cosθ = 0 (√sinθ − √cosθ)2 = 0 √sinθ = √cosθ Either cosθ or sinθ can be equal to zero. Both can't be equal to zero at the same time. As we can see that √sinθ = √cosθ, neither of cosθ and sinθ is equal to zero.
