WebbLet \( \mathrm{P}=\{\theta: \sin \theta-\cos \theta=\sqrt{2} \cos \theta\} \) and \( \mathrm{Q}=\{\theta: \sin \theta+\cos \theta=\sqrt{2} \sin \theta\} \) b... Webb19 juni 2024 · This can be proven by cross-multiplication: multiply both sides by cos(θ)(1 − sin(θ)), i.e. by both denominators to get. On the right hand side we have the expression (a + b)(a −b) = a2 −b2, so the expression becomes. Which is true, because it derives immediately from the fundamental trigonometric equation.
