Question

6 tan^2 45o + 6 sec^2 30o tan^2 60o by sin^2 60o + cos^2 60o

Answer 1

Answer:

Water boils at 100°C, becoming a gas(steam). In contrast, LPG boils at -42°C becoming gas vapour. The process of going from liquid to vapour (gas) iscalled vaporisation. LPG stays liquid because it is under LPG pressure in agas cylinder.29-Apr-2021

Answer 2

1 + 6 – 3 + 2. = 6. Example 23.4: Verify that. 0. 0 cos 2. 90sin 5. 45 cot. 60 sec. 30 cosec. 45 tan o o o o o o. = −. +. Solution: L.H.S. = o o o o o o. 0 cos 2. 90 sin 5.
