refer to the following: The bifolium is a curve that can be drawn using either an algebraic equation or an equation involving trigonometric functions. Even though the trigonometric equation uses polar coordinates, its much easier to solve the trigonometric equation for function values than the algebraic equation. The graph of is shown below. Youll see more on polar coordinates and graphs of polar equations in Chapter 8. The following graph is in polar coordinates.Bifolium.The equation for the bifolium shown on the left is Use a Pythagorean identity to rewrite the equation using only the function Then nd r if u = 30, 60, and 90.
