If `acos^2(C/2)+c cos^2(A/2)=(3b)/2`. To prove: `cot(A/2),cot(B/2),cot(C/2)` are in A.P.

If a cos^(2)((C)/(2))+c cos^(2)((A)/(2))=(3b)/(2). To prove: cot((A)/(2)),cot((B)/(2)),cot((C)/(2)) are in

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,cot((A)/(2)),cot((B)/(2)),cot((C)/(2)) are in A.P.

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

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

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

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