WebThe general equation of a circle normally appears in the form \({x^2} + {y^2} + 2gx + 2fy + c = 0\) where \(( - g, - f)\) is the centre of the circle and \(\sqrt {{g^2} + {f^2} - c}\) is the radius. WebBy thinking of the sine and cosine values as coordinates of points on a unit circle, it becomes clear that the range of both functions must be the interval [ − 1, 1 ]. In both graphs, the shape of the graph repeats after 2 π, which means the functions are periodic with a period of 2 π. sims 4 maxis match cc baby hair
