Cos 48degree minus sin 42 degree |
|
Answer» ONG>Step-by-step explanation: Evaluate Cos 48 degree - SIN 42 degree. Answer: 0 To find Cos 48o – Sin 42o We know that Cos (90 – θ) = Sin θ……..(1) So we can write Cos 48o as Cos 48o = Cos (90 – 42) Cos 48o = Cos (90 – 42) = Sin 42o………(2) Cos 48o – Sin 42o From equation (2) we can write the above equation as Sin 42o – Sin 42o = 0 |
