怎样用MATLAB 或者 maple求解符号方程组
怎样用软件实现下列方程组的解啊
syms x y R a b
>> [a,b]=solve('R*cos(a)-R*cos(a+b)=x','R*sin(a)-R*sin(a+b)=y','a,b')
Warning: Explicit solution could not be

我用的是matlab5.3
通过上述的表达式,有解的
[a,b]=solve('R*cos(a)-R*cos(a+b)=x','R*sin(a)-R*sin(a+b)=y','a,b')
a =

b =

您可以通过SIMPLE,SIMPLIFY,FACTOR,EXPAND,COLLECT等函数来化简
