यदि \(\theta\) चतुर्थ चतुर्थांश में है और \(\cos \theta=\frac{8}{17}\), तो \(\tan \theta\) क्या होगा?
If \(\theta\) is in the fourth quadrant and \(\cos \theta=\frac{8}{17}\), what will \(\tan \theta\) be?
Correct answer and explanation
C. \(-\frac{15}{8} \)
Simple Explanation
चतुर्थ चतुर्थांश में \(\sin \theta\) ऋणात्मक और \(\cos \theta\) धनात्मक होता है। इसलिए \(\sin \theta=-\frac{15}{17}\) और \(\tan \theta=-\frac{15}{8}\)। / In the fourth quadrant, \(\sin \theta\) is negative and \(\cos \theta\) is positive. Hence \(\sin \theta=-\frac{15}{17}\) and \(\tan \theta=-\frac{15}{8}\).
