WebIt is also true that cos (½π-x) = sin (x) and that cos (x- ½π) = sin (x) So, cos (½π-x) = cos (x- ½π) Sine and cosine are both periodic functions that are identical except for being shifted ½π radians out of phase. Thus, there are a number of ways you can shift them around to be in phase and therefore equal. WebThis value is the ratio of the circumference of a circle to its diameter and is called π (Pi).
