In any `Delta ABC` , `cot(A/2),cot(B/2),cot(C/2)` are in `A.P.`, then

In any !ABC ,If cot(A/2),cot(B/2),cot(C/2) are in A.P.,then a,b,c are in

In any Delta ABC , If cot ""A/2 , cot ""B/2 ,cot ""C/2 are in AP, then a,b,c are in

In any Delta ABC , If cot ""A/2 , cot ""B/2 ,cot ""C/2 are in AP, then a,b,c are in (A) A.P, (b)G.P., (c)H.P., (d)NONE OF THESE

In any Delta ABC , If cot ""A/2 , cot ""B/2 ,cot ""C/2 are in AP, then a,b,c are in (a) AP (b) GP (c) HP (d) None of these

If a, b, c are in A.P then cot(A/2),cot(B/2),cot(C/2) are in

In Delta ABC, if cot""A/2,cot""B/2,cot""C/2 are in A.P. then a,b,c are In

In a triangle ABc , if r^2cot(A/2) cot(B/2) cot(C/2)=

In any /_ABC(cot A)/(2),(cot B)/(2),(cot c)/(2) are in A.P.then

If the side lengths a,b and c are in A.P. prove that cot (A/2),cot (B/2),cot (C/2) are in A.P .

In Delta ABC, cot ""(A)/(2) +cot""(B)/(2) + cot""(C)/(2)=
