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: \(\sin \theta\)\(\sin \theta\)
\(\cos\left(\frac{3\pi}{2}+\theta\right)=\sin \theta\). In the fourth quadrant, \(\cos \theta\) is taken as positive.\(\cos\left(\frac{3\pi}{2}+\theta\right)=\sin \theta\) होता है। चौथे चतुर्थांश में \(\cos \theta\) धनात्मक माना जाता है।
