evaluate the cot%2837pi%2F6%29............pi%2F6=30 degrees

cot%2837%2A30%29=cot%281110%29...=> cot will be same as cot%2830%29 degrees
write cot%2830%29 as cos%2830%29%2Fsin%2830%29
=cos%2830%29%2Fsin%2830%29

=%28sqrt%283%29%2F2%29%2F%281%2F2%29

=%28sqrt%283%29%2Fcross%282%29%29%2F%281%2Fcross%282%29%29

=sqrt%283%29=1.73
