Coordinates are used to describe the position of points on a grid. The main horizontal line on the grid is known as the x-axis and the main vertical line is the y-axis. Both axes are number lines ...

The axes will include all given coordinate values of 𝒙 and 𝒚. The scales used depends on the values of 𝒙 and 𝒚, and on the available grid. Both the grids can be used to plot a maximum ...

Express the polar equation \(r=\cos 2\theta\) in rectangular coordinates. Find the maximum height above the \(x\)-axis of the cardioid \(r=1+\cos \theta\text{.}\) Sketch the graph of the curve whose ...
