i want to find the minimum sum of this equation and find the t like using solver in Excel,but since the integration cannot be integrate directly,i didnt know how to use the numerical integration to apply for this problem.(adsbygoogle = window.adsbygoogle || []).push({});

i want to find the value :let say when n=2, t_0=0 and t_n=1, so i need to find t_1 that will make the equation become minimum value.I hope that anyone can help me.

Sum[Integrate[4.9*^6*E^(-0.03*t + 0.03*(t + Subscript[t, j]))*

((1 - 0.015*(6 + t))/E^(0.015*Subscript[t, j]) +

(-0.91 + 0.015*Subscript[t, j])/E^(0.015*t))^2,

{t, Subscript[t, -1 + j], Subscript[t, j]}], {j, 1, n}]
