Detailed Solution
Download Solution PDFপ্রদত্ত:
\(\frac{\tan 71^{\circ}+\tan 19^{\circ}}{1-\tan 71^{\circ} \tan 19^{\circ}}\)
ব্যবহৃত সূত্র:
\(\tan(A+B) = \frac{\tan A + \tan B}{1 - \tan A \tan B}\)
গণনা:
\(A = 71^{\circ}\) এবং \(B = 19^{\circ}\) ব্যবহার করে, আমরা অভেদটিতে প্রয়োগ করি:
⇒ \(\tan(71^{\circ} + 19^{\circ}) = \tan 90^{\circ}\)
আমরা জানি যে \(\tan 90^{\circ}\) অনির্দিষ্ট
∴ প্রদত্ত রাশিটি সরলাকৃত মান অনির্দিষ্ট
