If `A,B` and `C` are in A.P then correct relation is

If A,B,C are in A.P., then correct relation is cot A=(sin B+sin C)/(cos C+sin B)

If a,b,c are in A.P. then

If a,b,c are in A.P. then :

if a, b,c are in A.P. then b =

If a, b, c are in A.P. as well as in G.P. then correct statement is :

If a, b, c are in A.P. as well as in G.P. then correct statement is :

If a, b, c are in A.P. then prove that the following are also in A.P:(iii) (1)/(a)((1)/(b)+(1)/(c )),(1)/(b)((1)/(c )+(1)/(a)),(1)/(c )((1)/(a)+(1)/(b)) are in A.P

If a,b and c are in A.P, show that (b+c), (c+a) and (a+b) are also in A.P.

If a, b, c are in A.P. then show that the terms given below are also in A.P. b + c, c + a, a + b

If a, b, c are in A.P., then prove that : (i) b+c,c+a,a+b" are also in A.P." (ii) (1)/(bc),(1)/(ca),(1)/(ab)" are also in A.P." (iii) (a(b+c))/(bc),(b(c+a))/(ca),(c(a+b))/(ab)" are also in A.P."
