Graph the circle \(x^{2}+y^{2}=1\) with your graphing calculator. Use the feature on your calculator that allows you to evaluate a function from the graph to find the coordinates of all points on the circle that have the given \(x\)-coordinate. Write your answers as ordered pairs and round to four places past the decimal point when necessary.Graph the circle \(x^{2}+y^{2}=1\) with your graphing calculator.
