if cosA = 1/root2, find the value of cotA

Cos A = 1/ root 2
 
Cos45 = 1/ root 2

A= 45
Cot A = Cot 45 = 1
=1

  • 2
cosA=1/root2
cos45​0=1/root2
A=45
cot 45 =1
the answer is 1...
  • 0
Cos A    =      1
                  --------
                     √2

we know,  1        =  cos 45
                ----
               
√2
thus,
cosA = cos 45
A = 450

CotA = Cot45
thus,
Cot 45 = 1  [ According to table provided in NCERT ]

thus, Cot A = 1

Hope you got it!
