| hi I have an integral in this form::: NIntegrate[ (5184*(-11 + k*(98 + k*(-16 + k*(-40 + k*(17 + 2*k*(7 + k)))))))/ ((1 + E^((1/2)*(-1 + k)))*(1 + k)^3*(-7 + k*(2 + k))^3), {k, 0, Infinity}] when i set ,... |
| yes my final result is numerical.NIntegrate is very fast but it`s answer is zero! it is not correct. where can i use NIntegrate? |
| thank you Udo Krause. very good answer. |
| hi i want use for loop in mathematica but i do not know what is the role of i++? i think this loop is equal to for i=1:4 print(i) end in matlab. Do I understand correctly? For[i = 0, i |
| I am new in Mathematica. in matlab i define a function as: f(x)=x+1 then if i type f(2) answer is 3. how can i do this in mathematica. |
