v1 v2 7 7 \[\max_{x \in [1, 1]}{\big\vert f(x)  P(x)\big\vert} = E\] 8 8 }}} 9 10 Where ''f(x) = exp(x)''. 9 11 10 12 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. … … 87 89 == Analysing the results == 88 90 89 Again, the two errorare undistinguishable:91 Again, the polynomial and the original function are undistinguishable: 90 92 91 93 [[Image(fastexp2.png, nolink)]] … … 99 101 == Conclusion == 100 102 101 You should now be able to weigh your error function to control where to minimise the error!103 You should now be able to weigh your error function to control the final error curve of the minimax polynomial! 102 104 103 Please report any trouble you may have had with this document to [sam@hocevar.net].
