Set your mathematical model be; y th = a*e^-bx a and observations

x y^abs
1 0.36790
2 0.13530
3 0.04980
4 0.01830
5 0.00670


(and its plot in there)

select several a's and b's such that a (0,005 to 0,005x350) b(0,005 0,005x350)

and calculate standart devinions of y abs - y th

then construct a matrix having the devisty and contour the values

1)decide the best values of a and b
2)justify your answer

--0,005ler x ve y düzleminde
