cosθ = 12/13 হলে, tanθ এর মান-

Explanation:

Another Explanation (5): ```html cosθ = 12/13 হলে, tanθ এর মান নির্ণয়: আমরা জানি, \(sin^2θ + cos^2θ = 1\) সুতরাং, \(sin^2θ = 1 - cos^2θ\) \(sin^2θ = 1 - (12/13)^2\) \(sin^2θ = 1 - 144/169\) \(sin^2θ = (169 - 144)/169\) \(sin^2θ = 25/169\) সুতরাং, \(sinθ = ±\sqrt{25/169}\) \(sinθ = ±5/13\) এখন, আমরা জানি, \(tanθ = sinθ / cosθ\) সুতরাং, \(tanθ = (±5/13) / (12/13)\) \(tanθ = ±5/13 * 13/12\) \(tanθ = ±5/12\) অতএব, \(tanθ\) এর মান \(±5/12\) 🥳🥳 ```
