Multiple choice general knowledge math & puzzles What is value of sinA*cosA*tanA*secA*sinB*cosB, if angle 1\2 1\2root2 1 0 Reveal answer Fill a bubble to check yourself D Correct answer Explanation Substitute the given angles: sin45° = 1/√2, cos45° = 1/√2, tan45° = 1, sec45° = √2, sin90° = 1, cos90° = 0. The expression becomes (1/√2) × (1/√2) × 1 × √2 × 1 × 0 = 0 because cos90° = 0. Any expression multiplied by zero equals zero. AI explanation AI 1 With ` Thanks Wrong explanation
