tan ( arctan x ) = x
cot x = 1 / tan x
tan ( arccot x ) = tan [ arc (1 / tan x ) ] = 1 / tan ( arctan x ) = 1 / x
tan ( arccot 2 ) = tan [ arc (1 / tan 2 ) ] = 1 / tan ( arctan 2 ) = 1 / 2
Evaluate the expression without using a calculator (Make a sketch of a right triangle)
tan(arccot 2)
Thanks in advance!
I'm trying to refresh my memory of these kinds of problems and I'm having trouble on how to solve this problem
