thanks bro
but little confusion how is root 3 cut by 3
bro if you multiply √3 and√3 then you get 3 so if you divide√3 by 3 then you"ll get 1/√3
√3tan♀=3sin♀. √3sin♀/cos♀=3sin♀, √3×1/cos♀=3, 1/cos♀=3/√3 then rationalization rhs now 1/cos♀=√3, √3cos♀=1, cos♀= 1/√3, then squaring both sides cos^2♀=1/3
then so on
but thank u so much
