Answer 2

To calculate the values of the trigonometric functions, we'll need to use a calculator. Please note that the angles provided (510, 1200, and 1005) are most likely in degrees. Trigonometric functions in calculators usually expect angles to be in radians, so we'll need to convert the angles from degrees to radians first.

1. Convert degrees to radians:

• cos(510°) = cos(510° * π / 180°) ≈ cos(8.89 radians)
• sin(1200°) = sin(1200° * π / 180°) ≈ sin(20.94 radians)
• tan(1005°) = tan(1005° * π / 180°) ≈ tan(17.57 radians)

2. Use a calculator to find the approximate values:

• cos(8.89 radians) ≈ -0.103
• sin(20.94 radians) ≈ -0.874
• tan(17.57 radians) ≈ -2.502

So, the approximate values are: cos(510) - sin(1200) - tan(1005) ≈ -0.103 - (-0.874) - (-2.502) ≈ 2.273
