Construct a 4 × 3 matrix A = [a_{i j}] whose elements a_{i j} are given by a_{i j} = i

Class 12 Maths Matrices View Answer

Construct a 4 × 3 matrix A = [ai j] whose elements ai j are given by \( a_{i j} = \dfrac{(i – j)}{(i + j)}\)

Accepted Answer

Given a_{i j} = 2i

Let A = [a_{i j}]_2×3

So, the elements in a 3×4 matrix are

a₁₁, a₁₂, a₁₃, a_14, a₂₁, a₂₂, a₂₃, a₂₄, a_31,a_32,a_33,a₃₄

a₁₁ = 2×1 = 2

a₁₂ = 2×1 = 2

a₁₃ = 2×1 = 2

a₁₄ = 2×1 = 2

a₂₁ = 2×2 = 4

a₂₂ = 2×2 = 4

a₂₃ = 2×2 = 4

a_{24 =} 2×2 = 4

a₃₁ = 2×3 = 6

a₃₂ = 2×3 = 6

a₃₃ = 2×3 = 6

a₃₄ = 2×3 = 6

Substituting these values in matrix A we get,
