Mathematics Questions
- Question 1: Let A and B be two square matrices of the same order. If AB = A and BA = B, then A² = A and B² = B.
- Question 2: Every square matrix can be expressed as a sum of a symmetric and a skew-symmetric matrix. If A is a non-singular matrix, adj A is also non-singular. (AB)C = A(BC) for any n x n matrices A, B, C. If AB = O (the null matrix), then A or B = O.
- Question 3: If A is a 4th-order matrix, then adj(adjA²) = |A|⁶.
- Question 4: If x = cy+bz, y = az+cx, z = bx+ay has a non-zero solution, then a²+b²+c²+2abc=0.
- Question 5: x²+x+1 / (x²+2x+1)(x+1)² = A + B / (x+1) + C / (x+1)²; (A, B, C) = (1, -1, 1).
- Question 6: If x, y, z are positive real numbers and logx (y/z) / (y-z) = logy (z/x) / (z-x) = logz (x/y) / (x-y), then xyz=1.
- Question 7: In triangle ABC, if cot A / (b+c) = cot B / (c+a) = cot C / (a+b), then ∠A+∠C=90°.
- Question 8: If cot A : cot B : cot C = 3:5:7, then a:b:c=5:4:6.
- Question 9: If A - B = 3π/4, then (1 - tan A)(1 + tan B) = 0.
- Question 10: √3 csc 20° sec 20° = 2.
- Question 11: cos A cos 2A cos 4A cos 8A = sin 16A / 16 sinA.
- Question 12: sin 2x + sin 4x = 2sin 3x; general solution is nπ/3 + 2nπ, n ∈ Z.
- Question 13: If x, y, z have same sign such that xy+yz+zx<1 and tan⁻¹x+tan⁻¹y+tan⁻¹z=π, then 1/xy+1/yz+1/zx = 1/xyz.
- Question 14: If sinh x = 5, then ex = 5 ± √26.
- Question 15: If a and β are distinct complex numbers such that (β-α)/(1-αβ) = 1, then |α| = 1 or |β| = 1.
- Question 16: If (1+sinθ+icosθ)/(1+sinθ−icosθ) = cos kθ + i sin kθ, then k=1.
