Teaching UP TGT Mock Test Series 2025 Mathematics Complex Numbers Algebraic Operations on Complex Numbers
यदि\({\left( {\frac{{\cos \theta + i\sin \theta }}{{\sin \theta + i\cos \theta }}} \right)^{2020}} + {\left( {\frac{{1 + \cos \theta + i\sin \theta }}{{1 - \cos \theta + i\sin \theta }}} \right)^{2021}} = x + iy\) है, तब \(\theta=\frac{\pi}{2}\) पर x + y का मान क्या है?
