[rohitram]

Sin(-420) Cos(390) + Cos(-660) Sin(330)
= -Sin(420) Cos(390)+ Cos(660) Sin(330)
=Sin(2π+60) Cos(2π+30) + Cos(4π-60) Sin(2π-30)
=-(Sin60 Cos30 + Cos60 Sin30)
= -(√3/2*√3/2 + 1/2*1/2 )
= -( 3/4 + 1/4 )
= -1
So, the correct answer is option :-
(D) -1
Thank you!!!

Great session sensei 🤓🔥

[adithyaram]

Rasengann 👍🔥🔥 Yet Another amazing Session Sir ❤️❤️
Homework Answer Is Option D (-1)
Sin(-420) (Cos 390) + Cos(-660) (Sin 330)
Since Sin(-θ) = - Sinθ
Cos(-θ) = Cosθ
-Sin(4.90+60) Cos(4.90+30) + Cos(8.90-60) Sin(4.90-30)
(-Sin60) (Cos30) - (Cos60) (Sin30)
(-√3/2) (√3/2) - (1/2) (1/2)
= -3/4 - 1/4
Final Answer Is -1 🔥🔥🔥
