If \(\theta=\cot^{-1}\left(\frac{3}{4}\right)\), what is the value of \(\cos\theta\)?यदि \(\theta=\cot^{-1}\left(\frac{3}{4}\right)\), तो \(\cos\theta\) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(\frac{3}{5}\)\(\frac{3}{5}\)
From \(\cot\theta=\frac{3}{4}\), the base is (3), perpendicular is (4), and hypotenuse is (5). Hence \(\cos\theta=\frac{3}{5}\).\(\cot\theta=\frac{3}{4}\) से आधार (3), लम्ब (4) और कर्ण (5) होगा। इसलिए \(\cos\theta=\frac{3}{5}\)।
