(Question numbers 1 to 6 carry 1 mark each)
1. Find the maximum value of
1 1 1
1 1 + sin 1
1 1 1 + cos
θθ
.
Solution. Operating R2 → R2 – R1 and R3 → R3 – R1, we get:
Δ =
1 1 1
0 sin 0
0 0 cos
θθ
= sin θ cos θ = 1
2sin 2 θ.
∴ Max. value of Δ = 1
2(1) = 1
2.
2. If A is a square matrix such that A2 = I, then find the simplified value of(A – I)3 + (A + I)3 – 7A.
Solution. (A – I)3 + (A + I)3 – 7A= A3 – I3 – 3 A2I + 3A I2 + A3 + I3 + 3A2I + 3AI2 –7A= 2A3 + 6AI2 – 7A = 2AA2 + 6A I – 7A= 2AI + 6A – 7A = 2A + 6A – 7A = A. [�A2 = I]
3. Matrix A =
