cot is cotangent...

anonymous · Answer

i still don't know what cot is ...

anonymous · Answer

cot x = 1/tan x --> it's the inverse of tangent 
csc x= 1/sin x
sec x = 1/cos x

campbell_st · Answer

from right angled trig you should know tan(x) = opp/adj. 
cot is another trig ratio and it is the reciprocal of tan. $$\cot(x) = \frac{1}{\tan(x)} = \frac{adj}{opp}$$
