`(cotB.cotA+1)/(cotB-cotA)= ....?`

If ((cotAcotB-1))/((cotB+cotA))=x then the value of x is

Prove that- cot(A+B)=(cotA.cotB-1)/(cotA+cotB)

If A+B =225^(@) then the value of (cotA)/(1+cotA).(cotB)/(1+cotB) is

If A+B+C=pi , prove that : (cotB+cotC) (cotC+cotA) (cotA+cotB)=cosecA cosecB cosecC

1/(cosecA+cotA)=cosecA-cotA

"(cotA+cosecA-1)"/"(cotA-cosecA+1)"=?

The value of (cosecA + cotA +1)(cosecA - cotA + 1) - 2cosecA is: (cosecA + cotA +1)(cosecA - cotA + 1) - 2cosecA का मान है :

Prove that (cotA- cosA)/(cotA+ cosA) = (cosecA -1)/(cosecA+1)

(cot A+tanB)/(cotB+tanA) is :
