Our results of cos2pi have been rounded to five decimal places. first of all, you need to know what is cosine. In simple words, if you take a circle of radius of 1 unit on any graph, then on the circumference of that circle, every x coordinate states the value of cosine and y coordinate stats the value of sine Trigonometry.
