Best ResponseYou've already chosen the best response.0Taylor Expansion is the way of estimating and function sinx is \[x\frac{ x ^{3} }{ 6 }+\frac{ x ^{5} }{ 120 } ...+...\]

Best ResponseYou've already chosen the best response.1u'll get a cubic equation, with one root = 0 (can't be, rejected) and 2 other roots.....from which u select one with positive value..... like saura said...
