What is \(\cot\left(\frac{\pi}{2}+\theta\right)\) equal to?\(\cot\left(\frac{\pi}{2}+\theta\right)\) किसके बराबर होता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: -\(\tan \theta\)-\(\tan \theta\)
The cofunction of \(\cot \theta\) is \(\tan \theta\), and the sign is negative in the second quadrant. In such questions, first identify the cofunction.\(\cot \theta\) का सह-फलन \(\tan \theta\) है और दूसरे चतुर्थांश में चिह्न ऋणात्मक होता है। ऐसे प्रश्नों में पहले सह-फलन पहचानें।
