mathematica,初学者的问题
[Pi] has a run of six consecutive 9's in the first 1000 digits.Can you see where they are located?(One way to find the location is to convert the number to a string [using ToString],drop the leading 3.[using StringDrop] and locating the position of the string "999999" [using StringPosition]).[3 Marks]
StringPosition[StringDrop[ToString[N[Pi,1000]],3],"999999"]
照英文的意思

Mathematica关于常解微分方程的问题求出p[t]后,题目是再求出p''[t]=0的时候的t1和p1,一点思路也没,毕竟自学...书上也找不到.DSolve[{p'[t] == 0.029 p[t] - 2.941*10^(-4) p[t]^2,p[0] == 30.6},p[t],t]
Mathematica求常解微分方程的一个问题输入:DSolve[{p'[t] == a p[t] - b p[t]^2, p[Subscript[t,0]] == Subscript[p,0]},p[t],t]为什么得到的还是原式 同时还有这一句话:DSolve::dvnoarg:The function p appears with no argumen
懂mathematica的进!
