Cos 225 degrees.

To find the value of cos 120 degrees using the unit circle: Rotate ‘r’ anticlockwise to form 120° angle with the positive x-axis. The cos of 120 degrees equals the x-coordinate (-0.5) of the point of intersection (-0.5, 0.866) of unit circle and r. Hence the value of cos 120° = x = -0.5.

For sin 450°, the angle 450° > 360°. Given the periodic property of the sine function, we can represent it as sin (450° mod 360°) = sin (90°). The angle 450°, coterminal to angle 90°, lies on the positive y-axis. Thus, sin 450 degrees value = 1. Similarly, sin 450° can also be written as, sin 450 degrees = (450° + n × 360°), n ∈ Z. cos 225 degrees = -√ (2)/2. The cos of 225 degrees is -√ (2)/2, the same as cos of 225 degrees in radians. To obtain 225 degrees in radian multiply 225° by π / 180° = 5/4 π. Cos 225degrees = cos (5/4 × π). Our results of cos225° have been rounded to five decimal places.

For cos 120 degrees, the angle 120° lies between 90° and 180° (Second Quadrant ). Since cosine function is negative in the second quadrant, thus cos 120° value = - (1/2) or -0.5. ⇒ cos 120° = cos 480° = cos 840°, and so on. Note: Since, cosine is an even function, the value of cos (-120°) = cos (120°).

cos 45° = √ (2)/2. cos 45 degrees = √ (2)/2. The cos of 45 degrees is √ (2)/2, the same as cos of 45 degrees in radians. To obtain 45 degrees in radian multiply 45° by π / 180° = 1/4 π.
