 v1 $\max_{x \in [-1, 1]}{\big\vert f(x) - P(x)\big\vert} = E$ }}} Where ''f(x) = exp(x)''. The final polynomial was such that ''E'' was approximately 0.000546277. More particularly, ''|exp(-1) - P(-1)|'' =  0.000546277 and  ''|exp(1) - P(1)|'' =  0.000546277. == Analysing the results == Again, the two error are undistinguishable: Again, the polynomial and the original function are undistinguishable: [[Image(fastexp2.png, nolink)]] == Conclusion == You should now be able to weigh your error function to control where to minimise the error! You should now be able to weigh your error function to control the final error curve of the minimax polynomial! Please report any trouble you may have had with this document to [sam@hocevar.net].
