If `A=B=C=1 and X= bar(ABC)+Bbar(CA)+Bbar(CA)+Cbar(AB)`, then X=

ABC is an equilateral triangle of side ‘a'. Then bar(AB).bar(BC) +bar(BC).bar(CA)+ bar(CA).bar(AB) =

If, in a right angled triangle ABC, the hypo tenus AB =p, then bar(AB).bar(AC)+bar(BC).bar(BA)+bar(CA).bar(CB) =

ABC is an equitateral triangle of side 'a'. Then bar(AB).bar(BC)+bar(BC).bar(CA)+bar(CA).bar(AB) =

In a right angled triangle ABC, hypotenuse AB=P then bar(AB).bar(AC)+bar(BC).bar(BA)+bar(CA).bar(CB) = ………

If A,B, C and D are four points, then show that |bar(AB) xx bar(CD) + bar(BC) xx bar(AD) + bar(CA) xx bar(BD)| is four times the area of Delta ABC

Prove the following boolean relations. bar(AB + BC + CA) = bar(A)bar(B) + bar(B)bar(C ) +bar(C)bar(A)

Let X=A bar(BC)+B bar(CA)+C bar(AB) .Evalute X for (a) A=1,B=0,C=1 (b) A=B=C=1 (c) A=B=C=0

Let X=A bar(BC)+B bar(CA)+C bar(AB) .Evalute X for (a) A=1,B=0,C=1 (b) A=B=C=1 (c) A=B=C=0

In DeltaABC, " if " BC = a, CA = b and AB = C, " then what is the value of " bar(AB).bar(AC)+bar(BC).bar(BA)+bar(CA).bar(CB) ?
