如果你完全安装后还出现这种情况,你可以先在添加删除程序里,修复下你安装的arcgis,确认已经安装了所有拓展(extensions),那很有可能是你没在拓展功能里没勾选它!
1.打开ArcMap,在菜单栏的tools--extensions,
2.勾选上你要的空间分析Spatial Analyst .
数列An中.An=2,An+1=An/An+3求An
已知数列{an}中,满足2an=3an-1 +4,求{an}
高手请进!ArcGIS9.2在vista下的安装问题,急!
an为等差数列,a1=2,d=2
等差数列(an) a2= -7 d=2
3:已知数列{An}中, An=1,A2=2,An+1=3An-2An-1,求通项An
用特征根法还能求An+3=An+2+An+1+An,或An+1=3^(n-1)-2An-1这样的通项?
已知数列an满足a1=1.a2=3,an+2=3an+1-2an
an+1=3an^2,a1=3,求an
a1=3,a2=6,an+2=(an+1)-an,求an2002
