    tan-¹(1) + cos-¹(-1/2) + sin-¹(-1/2) tan-¹= pie/4 cos-¹= 2pie/3 sin-¹= -pie/6 on adding them all.. pie/4+2pie/3+-pie/6= 9pie/12 =3pie/4 ... ans. *tan-¹(1) tan-¹(1)=y tan y=1 we know that range of tan-1= [-pie/2 , pie/2] so tan y=1=tan pie/4 y=pie/4 similarly repeat for othets also.. wishing you alll the best?
