Find the value of cos 48o – sin 42o
WebCorrect option is B) cos 248 o−sin 212 o=cos(48+12)cos(48−12)[cos 2A−sin 2B=cos(A+B)cos(A−B)] =cos60×cos36= 21× 4 5+1 8 5+1 Was this answer helpful? 0 0 … WebApr 2, 2024 · So, we get x = cos 48 ∘ − cos 48 ∘. ⇒ x = 0. So, we have found the value of cos 48 ∘ − sin 42 ∘ as 0. ∴ The value of cos 48 ∘ − sin 42 ∘ is 0. Note: Whenever we get this type of problem, we should try to convert both the trigonometric functions into the same trigonometric functions in order to reduce the calculation time.

WebSolution. sin 42° sin 48° - cos 42° cos 48°. = sin (90° - 48°)sin 48° - cos (90° - 48°)cos 48°. = cos 48° sin 48° - sin 48°cos 48°. = cos 48° sin 48° - cos 48° sin 48°. = 0. Concept: … WebWe know that, cos (90° − θ) = sin θ. So, cos 48° – sin 42° = cos (90° − 42°) – sin 42° = sin 42° – sin 42° = 0 . Thus the value of cos 48° – sin 42° is 0.
