Find all solutions of the equation.(Enter your answer in the form a + bπn,where a[0,2π),b is the smallest possible positive number,and n represents any integer.Round a to four decimal places.)
cot(x)=-0.237
x=?
我输入 arccot(-0.237)+ nπ 是错的...

题目：
解方程.（方程的解写成a+bπn的形式,其中a∈[0,2π),b是可能的最小正数,代表任意整数.a取四位小数.）
所以解没求错,只是要把arccot(-0.237)写成具体数值(取四位小数)才能合乎题目要求啊.查表吧 ^o^
