For the moment, just work with the displayed function and the four sliders in the bottom left corner. How do the fours sliders affect the graph?[br][br]Since the circle isn't a function, it has been graphed parametrically. Which trig function goes with the $ x $-coordinate of a given point and which one goes with the $ y $-coordinate? [br][br]Now click on the empty circle by the second parametric equation to display it. How do the sliders affect this shape? [br][br]What names does this graph suggest for our two new functions?
