`(a^(2)-b^(2))c+(b^(2)-c^(2))a`

If a, b, c are in G.P. , then show that (i) (a^(2) - b^(2))(b^(2) + c^(2)) = (b^(2) -c^(2)) (a^(2) + b^(2)) (ii) a( b^(2) + c^(2)) = c (a^(2) + b^(2))

Factorise : (a^(2)-b^(2))(a+b)+(b^(2)-c^(2))(b+c)+(c^(2)-a^(2))(c+a)

If a,b,c are in H.P., then (c^(2)(b-a)^(2)+a^(2)(c-b)^(2))/(b^(2)(a-c)^(2)) =

In triangle ABC,2ac sin((1)/(2)(A-B+C)) is equal to a^(2)+b^(2)-c^(2)(b)c^(2)+a^(2)-b^(2)b^(2)-c^(2)-a^(2)(d)c^(2)-a^(2)-b^(2)

If a,b,c,d are in G.P.show that: (ab+bc+cd)^(2)=(a^(2)+b^(2)+c^(2))(b^(2)+c^(2)+d^(2))

If a,b,c, and d are in G.P., show that (ab+bc+cd)^(2)=(a^(2)+b^(2)+c^(2))(b^(2)+c^(2)+d^(2)) .

If a,b,c and d are in G.P.show that (a^(2)+b^(2)+c^(2))(b^(2)+c^(2)+d^(2))=(ab+bc+cd)^(2)

If (a^(2)+b^(2)+c^(2))(b^(2)+c^(2)+d^(2))<=(ab+bc+cd)^(2) where a,b,c,d are non-zero real numbers,then they are in

In any DeltaABC , prove that (c^(2)-a^(2)+b^(2))tanA=(a^(2)-b^(2)+c^(2))tanB=(b^(2)-c^(2)+a^(2))tanC
