Example 3 Show that (ii) sinโ1 (2xโ(1โ๐ฅ2)) = 2 cosโ1x Solving L.H.S. sinโ1 ( 2x โ(1โ๐ฅ2) ) Putting x = cos ฮธ = sinโ1 ("2 cos ฮธ " โ(๐โ๐๐๐๐" ฮธ" )) = sinโ1 ("2 cos ฮธ " โ(๐๐๐๐" ฮธ" )) = sinโ1 (2 cos ฮธ sin ฮธ) = sinโ1 (sin 2ฮธ) We need to make 2x โ(๐โ๐๐) in terms of sin When we get โ(1โ๐ฅ2) , we put x = cos ฮธ or sin ฮธ
