In `DeltaABC`, `a^(2),b^(2),c^(2)` are in A.P. Prove that cotA, cotB, cotC are also in A.P.

If a^2,b^2,c^2 being A.P prove that cotA,cotB,cotC are also In A.P.

If a^2,b^2,c^2 are in A.P., prove that cotA ,cotB ,cotC are in AdotPdot

If a^2,b^2,c^2 are in A.P., prove that cotA ,cotB ,cotC are in AdotPdot

In DeltaABC , if a,b,c are in A.P. prove that: cot(A/2),cot(B/2), cot(C/2) are also in A.P.

If a^(2),b^(2) and c^(2) be in A.P. prove that cot A,cot B and cot C are in A.P. also.

If a^(2),b^(2) and c^(2) are in AP, then cotA, cotB and cotC are in

If a^(2),b^(2),c^(2) are in A.P. Prove that (a)/(b+c),(b)/(c+a),(c)/(a+b) are also in A.P.

if in a triangle ABC ,a^2,b^2,c^2 are in A.P. then show that cotA,cotB and cotC are also in A.P

In any triangle ABC, if tan (A/2), tan (B/2), tan (C/2) are in A.P., prove that, cosA, cosB, cosC are also in A.P.

IN any DeltaABC prove that if a^(2),b^(2) and c^(2) are in AP, the cotA, cotB and cotC are also is AP.
