evaluate cos 48° cos 42° - sin 48° sin 42° - Brainly.in
2018年1月6日 · We have to evaluate cos 48° cos 42° - sin 48° sin 42° We know that, cos (A+B) = cos A cos B - sin A sin B Here, A = 48° and B = 42° Hence, with the help of the formula given above, we can write cos 48° cos 42° - sin 48° sin 42° = cos (48° + 42°) cos 48° cos 42° - sin 48° sin 42° = cos 90° cos 48° cos 42° - sin 48° sin 42° = 0 (∵ cos 90°=0) This is the required …
