Answer 2

To calculate the expression cos(29°) × cos(1°) - cos(44°) × cos(16°), we can substitute the values of cos(29°), cos(1°), cos(44°), and cos(16°) into the equation and perform the arithmetic. Here's the calculation:

cos(29°) ≈ 0.8839 cos(1°) ≈ 0.9998 cos(44°) ≈ 0.7193 cos(16°) ≈ 0.9613

Substituting these values into the equation, we have:

0.8839 × 0.9998 - 0.7193 × 0.9613

Performing the multiplication and subtraction:

≈ 0.8837 - 0.6921

≈ 0.1916

Therefore, cos(29°) × cos(1°) - cos(44°) × cos(16°) ≈ 0.1916.
