The correct Answer is:

C

If cot A =2, then sec^2 A -1=
Text Solution
|
cot^(2)A((sec A-1)/(1+sin A))+sec^(2)A((sin A-1)/(1+sec A))=0
Text Solution
|
(cotA-1)/(2-sec^2A)=cotA/(1+tanA)
Text Solution
|
(cot A-1)/(2-sec^(2)A)=(cot A)/(1+tan A)
Text Solution
|
(cotA-1)/(2-sec^2A)=(cotA)/(1+tanA)
Text Solution
|
(cot A-1)/(2-sec^(2)A)=(cot A)/(1+tan A)
Text Solution
|
Prove: (cot^2A(secA-1))/(1+sinA)=sec^2A((1-sinA)/(1+secA))
Text Solution
