Detailed Solution
Download Solution PDFপ্রদত্ত :-
\(\rm \frac{\cos 13^{∘}+\sin 13^{∘}}{\cos 13^{∘}-\sin 13^{∘}}\)
ব্যবহৃত সূত্র :-
tanθ = \(\frac{sin\theta}{cos\theta}\)
গণনা :-
\(\rm \frac{\cos 13^{∘}+\sin 13^{∘}}{\cos 13^{∘}-\sin 13^{∘}}\)
cos13° দ্বারা লব ও হর ভাগ করলে পাই
এখন,
⇒ \(\frac{1 +\frac{sin13°}{cos13°}}{1 - \frac{sin13°}{cos13°}}\)
⇒ \(\frac{tan\frac{\pi}{4} + tan13°}{1 - tan\frac{\pi}{4} \times tan13°}\)
⇒ \(tan(45°+ 13°)\)
⇒ tan58°
