>> syms m;
int(int('((t-x)^2+(m-y)^2+n^2)^(-2)','t','-538+1.8*n','538-1.8*n'),'m',0,40)
运行时出现如下提示：
Warning: Explicit integral could not be found.
> In sym.int at 58
In char.int at 9
Warning: Explicit integral could not be found.
> In sym.int at 58
ans =
int(int(1/((t-x)^2+(m-y)^2+n^2)^2,t = -538+1.8*n .. 538-1.8*n),m = 0 .. 40)
请问各位这样的积分如何求啊？
