What is \(\sec\left(\frac{\pi}{2}+\theta\right)\) equal to?\(\sec\left(\frac{\pi}{2}+\theta\right)\) किसके बराबर होता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: -\(\cosec \theta\)-\(\cosec \theta\)
The cofunction of \(\sec \theta\) is \(\cosec \theta\), and \(\sec \theta\) is negative in the second quadrant. Hence the value is \(-\cosec \theta\).\(\sec \theta\) का सह-फलन \(\cosec \theta\) है और दूसरे चतुर्थांश में \(\sec \theta\) ऋणात्मक होता है। इसलिए मान \(-\cosec \theta\) है।
