一道很简单的三角函数题,但就是做错,
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...

第一项有问题吧.arccot(-0.237) 就是你指的a是吧?看清楚a是0到2pi之间.不满足条件吧,arccot(-0.237)本来就多解,如果非要那样得话,何必加Npi呢.
