If (\cot \theta=\frac{12}{5}) and (\theta) is in the first quadrant, what is (\cos \theta)?यदि (\cot \theta=\frac{12}{5}) और (\theta) प्रथम चतुर्थांश में है, तो (\cos \theta) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\frac{12}{13})(\frac{12}{13})
In ( \cot \theta=\frac{12}{5}), adjacent is (12), opposite is (5), and hypotenuse is (13). In exams use ( \cos \theta=\frac{\text{adjacent}}{\text{hypotenuse}}).(\cot \theta=\frac{12}{5}) में adjacent (12), opposite (5), hypotenuse (13) है। परीक्षा में (\cos \theta=\frac{\text{adjacent}}{\text{hypotenuse}}) लगाएं।
