What is \(\cos\left(\frac{\pi}{2}-\theta\right)\) equal to?\(\cos\left(\frac{\pi}{2}-\theta\right)\) किसके बराबर होता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(\sin \theta\)\(\sin \theta\)
\(\cos\left(\frac{\pi}{2}-\theta\right)=\sin \theta\). In cofunction relations, \(\sin \theta\) and \(\cos \theta\) interchange.\(\cos\left(\frac{\pi}{2}-\theta\right)=\sin \theta\) होता है। सह-फलन संबंध में \(\sin \theta\) और \(\cos \theta\) आपस में बदलते हैं।
