Extracted text: The values of error function, erf(x), are presented in the table. a) Use the appropriate strategy (shortly explain why it is appropriate) and fit a curve to this data. b) Use the fitted curve to calculate the value of x that satisfy erf(x)=0.5 with &=0.1%. erf (x) 0.25 0.2763 0.5 0.5205 0.75 0.7112 0.8427 Note: For part a) don’t use linear splines. For part b) you can use any technique of your choice. Fast converging methods are advised. 1.
