`((1-cot A)/(1-tan A))^(2)=cot^(2)A`

((1-cot A)/(1-tan A))^(2)=cot^(2)A
Text Solution
|
(cotA-1)/(2-sec^2A)=cotA/(1+tanA)
Text Solution
|
cot A=(1)/(2)(cot((A)/(2))-tan((A)/(2)))
Text Solution
|
((1+tan^2A)/(1+cot^2A))=((1-tanA)/(1-cotA))^2=tan^2A
Text Solution
|
(cot A-1)/(2-sec^(2)A)=(cot A)/(1+tan A)
