Design a logical circuit using AND, OR and NOT gatesto evaluate `A bar(BC)+B bar(CA)`.

Design a logical circuit using AND, OR and NOT gate to evaluate A bar(BC)+B bar(CA) .

A point I is the centre of a circle inscribed in a triangle ABC then show that abs(bar(BC))bar(IA)+abs(bar(CA))bar(IB)+abs(bar(AB))bar(IC)=bar(0)

If A(2, 2), B(6, 3) and C(4, 11) are vertices of a triangle ABC and D, E are the midpoints of bar(BC) and bar(CA) respectively, then the length of bar(DE) is

If bar(AD),bar(BE) and bar(CF) " are the medians of " DeltaABC , then find the value of bar(BC).bar(AD)+bar(CA).bar(BE)+bar(AB).bar(CF) .

If AD, BE and CF are the medians of DeltaABC , then the value of bar(BC).bar(AD)+bar(CA).bar(BE)+bar(AB).bar(CF)=

Assertion: The following circuit represents 'OR' gate Reason: For the above circuit Y=bar(X)=bar(bar(A+B))=A+B

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) =

Which logic gate corresponds to the logical equation Y =bar(A+B) ?
