解参数方程问题
本帖最后由 ljelly 于 2009-4-27 11:01 编辑symsw1 w2 t alpha r1 r2;
f=w2*r2*cos(w2*t)-w1*r1*cos(w1*t+alpha);
solve(f,'w2');
??? Error using ==> solve
Unable to find closed form solution.
Error in ==> sym.solve at 49
= solve(S{:});
:'(
是不是意味着没有解析解只有数值解啊????? 从方程的形式来看,这个方程是应该是个超越方程,很难求出w2的解析表达式,最好求解数值解! >> solve(f,'w2')
Warning: Explicit solution could not be found. 多谢多谢
