दिया गया है:

\(\frac{\tan 71^{\circ}+\tan 19^{\circ}}{1-\tan 71^{\circ} \tan 19^{\circ}}\)

प्रयुक्त सूत्र:

\(\tan(A+B) = \frac{\tan A + \tan B}{1 - \tan A \tan B}\)

गणना:

\(A = 71^{\circ}\) और \(B = 19^{\circ}\) का उपयोग करके, हम पहचान लागू करते हैं:

\(\tan(71^{\circ} + 19^{\circ}) = \tan 90^{\circ}\)

हम जानते हैं कि \(\tan 90^{\circ}\) अपरिभाषित है। 

∴ दिया गया व्यंजक अपरिभाषित तक सरलीकृत होता है।
