To find the cosine of a specific angle, you can use a scientific calculator or refer to the unit circle. For example, the cosine of 0 degrees (or 0 radians) is 1, while the cosine of 90 degrees (or π/2 radians) is 0. Additionally, you can use trigonometric identities or tables for common angles such as 30 degrees (√3/2), 45 degrees (√2/2), and 60 degrees (1/2).

How do you use calculator to find cos degrees?
To find the cosine of an angle in degrees using a calculator, first ensure that the calculator is set to degree mode (not radians). Enter the angle in degrees, then press the "cos" button. The calculator will display the cosine value for that angle. For example, to find cos(60°), input 60, select "cos," and the result will be 0.5.

What is the exact value of sin 255?
To find the exact value of sin 255°, we can use the sine subtraction formula. Since 255° = 270° - 15°, we can express it as: [ \sin(255°) = \sin(270° - 15°) = \sin(270°) \cos(15°) - \cos(270°) \sin(15°. ] Knowing that (\sin(270°) = -1) and (\cos(270°) = 0), we have: [ \sin(255°) = -1 \cdot \cos(15°). ] Thus, the exact value of (\sin(255°) = -\cos(15°)).
