What is the value of \(\cot\left(\cos^{-1}\left(\frac{5}{13}\right)\right)\)?\(\cot\left(\cos^{-1}\left(\frac{5}{13}\right)\right)\) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(\frac{5}{12}\)\(\frac{5}{12}\)
If \(\theta=\cos^{-1}\left(\frac{5}{13}\right)\), then \(\cos\theta=\frac{5}{13}\) and \(\sin\theta=\frac{12}{13}\). Hence \(\cot\theta=\frac{5}{12}\).यदि \(\theta=\cos^{-1}\left(\frac{5}{13}\right)\), तो \(\cos\theta=\frac{5}{13}\) और \(\sin\theta=\frac{12}{13}\)। इसलिए \(\cot\theta=\frac{5}{12}\)।
