一个maple问题
在maple中运算:f1:=5*(1+cos(theta))/(2+2*cos(theta))^(1.5);
int(f1,theta=0..2*pi);
运算提示:
arning, unable to determine if 2*Pi*_Z7 is between 0 and 2*pi; try to use assumptions or set _EnvAllSolutions to true
请问大侠们这里的2*Pi*_Z7 指的是什么? 我的f1该怎么积分? int(f1, theta = 0 .. 2*pi, 'AllSolutions') :time: ~~~~~~~~~~~,试一下! 定积分有点问题:
int((5*(1+cos(theta)))/(2+2*cos(theta))^1.5, theta);

定积分有点问题:
什么意思?不太明白
