If `A+B+C=180^@` , then `(cotA+cotB+cotC)/(cotAcotBcotC)` is

If A+B+C=pi/2 , show that : cotA+cotB+cotC=cotA cotB cotC

If A+B+C=pi/2 , show that : cotA+cotB+cotC=cotA cotB cotC

If A+B+C=pi//2 , show that cotA+cotB+cotC=cotAcotBcotC

If A+B+C=180^@ then the value of (cotB+cotC)(cotC+cotA)(cotA+cotB) will be

In a triangle A+B+C=90 then prove that cotA+cotB+cotC=cotAcotBcotC

If A+B+C = pi , prove that : cotAcotBcotC=cotA+cotB +cotC-cosecAcosecBcosecC.

If A + B + C= 180^@ , prove that (cot A+cotB)/(tanA+tanB)+(cotB+cotC)/(tanB+tanC)+(cotC+cotA)/(tanC+tanA)=1

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