In math-land, a circle begins at 3 o’clock, so noon is actually minus 90 degrees from that, which is 270 degrees (360 - 90). Let’s add another variable, --_d, that we can use to set a degree value for each number on the clock face. We’re going to increment the values ...
Cosine 360 or cos 360 is a trigonometric function that symbolizes a function in the fourth quadrant. As 360 degrees indicate complete rotation in the xy plane, the values from 270 degrees to 360 degrees are always positive. To be accurate the value of cos 360 is 1. The function oftrigonome...
Cos 120 degree is equal to minus half which can be written as (- ½ ) or (-0.5). Cos is one of the functions of Trigonometry that deals with the relationship between the angles and sides of a right-angled triangle. So in short, we can say that measuring a triangle (specifically ri...
