Question

急求，如何用matlab解下面这个三角函数方程组的解

24282557.3*tan(0.5*a)*tan(0.5*b)-35974085.3*tan(0.5*a)-25206029.4*tan(0.5*b)=18472644
1024441.7*tan(0.31*a)*tan(0.31*b)+5447993.34*tan(0.31*a)+5331932.755*tan(0.31*b)=16959129.83
a和b在1-10之间的

Answer 1

syms a b

[a,b]=solve('24282557.3*tan(0.5*a)*tan(0.5*b)-35974085.3*tan(0.5*a)-25206029.4*tan(0.5*b)=18472644','1024441.7*tan(0.31*a)*tan(0.31*b)+5447993.34*tan(0.31*a)+5331932.755*tan(0.31*b)=16959129.83')

a =
-25.845985006518124088166033714856
b =
37.405182853785968383691534379009
a和b好像不在1-10之间，是不是方程数据有误
