What is the value of \(\sin\left(\cos^{-1}\frac{3}{5}\right)\)?\(\sin\left(\cos^{-1}\frac{3}{5}\right)\) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(\frac{4}{5}\)\(\frac{4}{5}\)
Let \(\theta=\cos^{-1}\frac{3}{5}\), then \(\cos\theta=\frac{3}{5}\) and \(\theta\in[0,\pi]\). Here \(\sin\theta=\frac{4}{5}\).मान लें \(\theta=\cos^{-1}\frac{3}{5}\), तब \(\cos\theta=\frac{3}{5}\) और \(\theta\in[0,\pi]\)। यहां \(\sin\theta=\frac{4}{5}\) होगा।
