matlab怎么解决这个方程等于0时x的值呢,谢谢(cos(a+x)*cos(c+x)*cos(a-b))/(sin(a+c+d+x)*cos(b+x)*cos(a)^2)-(sin(a+x)*sin(c+x)*cos(a-b))/(sin(a+c+d+x)*cos(b+x)*cos(a)^2)+(cos(c+x)*sin(a+x)*sin(b+x)*cos

matlab怎么解决这个方程等于0时x的值呢,谢谢
(cos(a + x)*cos(c + x)*cos(a - b))/(sin(a + c + d + x)*cos(b + x)*cos(a)^2) - (sin(a + x)*sin(c + x)*cos(a - b))/(sin(a + c + d + x)*cos(b + x)*cos(a)^2) + (cos(c + x)*sin(a + x)*sin(b + x)*cos(a - b))/(sin(a + c + d + x)*cos(b + x)^2*cos(a)^2) - (cos(a + c + d + x)*cos(c + x)*sin(a + x)*cos(a - b))/(sin(a + c + d + x)^2*cos(b + x)*cos(a)^2)

Answer 1

在命令窗口输入
syms a x c b d
solve('(cos(a + x)*cos(c + x)*cos(a - b))/(sin(a + c + d + x)*cos(b + x)*cos(a)^2) - (sin(a + x)*sin(c + x)*cos(a - b))/(sin(a + c + d + x)*cos(b + x)*cos(a)^2) + (cos(c + x)*sin(a + x)*sin(b + x)*cos(a - b))/(sin(a + c + d + x)*cos(b + x)^2*cos(a)^2) - (cos(a + c + d + x)*cos(c + x)*sin(a + x)*cos(a - b))/(sin(a + c + d + x)^2*cos(b + x)*cos(a)^2)=0','x')
输出答案为
2*atan(z) + 2*pi*k
