(cos5^o + sin5^o)/(cos5^o - sin5^o) এর মান- 

Explanation:

Another Explanation (5): bài giải: \( \frac{cos5^\circ + sin5^\circ}{cos5^\circ - sin5^\circ} \) 🤓 আমরা লব ও হরকে \( cos5^\circ \) দিয়ে ভাগ করি। 😜 \( = \frac{\frac{cos5^\circ}{cos5^\circ} + \frac{sin5^\circ}{cos5^\circ}}{\frac{cos5^\circ}{cos5^\circ} - \frac{sin5^\circ}{cos5^\circ}} \) 🧐 \( = \frac{1 + tan5^\circ}{1 - tan5^\circ} \) 🤩 আমরা জানি, \( tan45^\circ = 1 \) 🤗 সুতরাং, \( = \frac{tan45^\circ + tan5^\circ}{1 - tan45^\circ tan5^\circ} \) 🤫 আমরা জানি, \( tan(A + B) = \frac{tanA + tanB}{1 - tanA tanB} \) 😎 অতএব, \( = tan(45^\circ + 5^\circ) \) 😇 \( = tan50^\circ \) 😉
