त्रिकोणमितीय नित्यसमीकरण वापरण्यासाठी दिलेले समीकरणचा वर्ग करू \( \sin \theta + \cos \theta = \sqrt{3}\) :
\( (\sin \theta + \cos \theta)^2 = (\sqrt{3})^2\)
\( \sin^2 \theta + 2 \sin \theta \cos \theta + \cos^2 \theta = 3\)
पायथागोरियन समीकरण वापरणे \(\sin^2 \theta + \cos^2 \theta = 1\) :
\( 1 + 2 \sin \theta \cos \theta = 3 \\ 2 \sin \theta \cos \theta = 2 \\ \sin \theta \cos \theta = 1 \)
आपल्याला माहित आहे की -
\(\tan \theta + \cot \theta = \frac{\sin \theta}{\cos \theta} + \frac{\cos \theta}{\sin \theta} \)
पायथागोरियन समीकरण वापरणे \(\sin^2 \theta + \cos^2 \theta = 1\) आणि \( \sin \theta \cos \theta = 1 :\)
\( \tan \theta + \cot \theta = \frac{1}{1} = 1 \)
म्हणून, \( \tan \theta + \cot \theta = 1 .\)
