What is \(\cos\left(\frac{3\pi}{2}-\theta\right)\) equal to?\(\cos\left(\frac{3\pi}{2}-\theta\right)\) किसके बराबर होता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: -\(\sin \theta\)-\(\sin \theta\)
With \(\frac{3\pi}{2}\), \(\cos \theta\) changes to the cofunction \(\sin \theta\). In the third quadrant, \(\cos \theta\) is negative.\(\frac{3\pi}{2}\) के साथ \(\cos \theta\) सह-फलन \(\sin \theta\) में बदलता है। तीसरे चतुर्थांश में \(\cos \theta\) ऋणात्मक होता है।
