x*sin(0.55/x)+x-0.55=0使用的办法也告诉我,最好用matlab吧.只要解出来就行xy*sin(0.55/xy)+x-0.55=0对y循环赋值1至50得到50个x，
x*sin(0.55/x)+x-0.55=0
使用的办法也告诉我,最好用matlab吧.只要解出来就行
xy*sin(0.55/xy)+x-0.55=0
对y循环赋值1至50得到50个x，

x*sin(0.55/x)+x-0.55=0使用的办法也告诉我,最好用matlab吧.只要解出来就行xy*sin(0.55/xy)+x-0.55=0对y循环赋值1至50得到50个x，
解超越方程应该有附近的初始值,这样才能用MATLAB算的

sin(0.55/x)=0.55/x-1再往下解你会不？

可以用几何画板得出y=1到50所对应的x的50个值

（下面是这50个值，并附上y=1和y=10时的两个图像。）

y=1~10,x=0.28,0.18,0.14,0.12,0.10,0.09,0.08,0.08,0.07,0.07;

y=11~20,x=0.06,0.06,0.05,0.05,0.05,0.05,0.04,0.04,0.04,0.04;

y=21~30,x=0.04,0.04,0.04,0.04,0.04,0.04,0.04,0.03,0.03,0.03;

y=31~40,x=0.03,0.03,0.03,0.03,0.03,0.03,0.03,0.03,0.03,0.03;

y=41~50,x=0.03,0.03,0.02,0.02,0.02,0.02,0.02,0.02,0.02,0.02.
