Cos (450 o) = 0
Although you may learn trig. functions between 0 and 90 ( or 180 , or 360), it is a cyclic wave like function and repeats every 360 degrees, in both the positive and negative directions, to infinity.
The word 'Sine(Sin)' comes from Latin and means 'curve'. Similarly, the word 'Cosine(Cos)' means Complementary Sine(Curve).

What is cos(22 degrees)?
cos(22) is a trigonometric ratio and, if the angle is measured in degrees, its value is 0.9272
What is equivalent to cos 150 degrees?
The cosine of 150 degrees is equivalent to the cosine of 180 degrees minus 30 degrees, which can be expressed as (-\cos(30^\circ)). Since (\cos(30^\circ) = \frac{\sqrt{3}}{2}), it follows that (\cos(150^\circ) = -\frac{\sqrt{3}}{2}). Therefore, (\cos 150^\circ = -\frac{\sqrt{3}}{2}).

What is cos 45 degrees?
Usually you can get the sine or cosine of an angle from a calculator very quickly. However, many calculators won't tell you that the result, which is about 0.707, is exactly 1 / square root of 2, or the equivalent square root of 2 / 2.
Determine the measure of angle A if 0 degrees is smaller than or equal to A which is smaller than or equal to 90 degrees and cos125 degrees equals negative cos A?
cos(125) = cos(180 - 55) = cos(180)*cos(55) + sin(180)*sin(55) = -cos(55) since cos(180) = -1, and sin(180) = 0 So A = 55 degrees.
