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 ...

FIG. 1 6: Cartesian and polar representation of a point. FIG. 1 7: Unit vectors in polar coordinates. Thus, if the Cartesian coordinates are known, the polar coordinates for the same point can be ...

Volumes using cross-sections, the disk method, the washer method and the shell method. Arc length and surface area. Infinite series, power series, Maclaurin and Taylor series. Polar coordinates and ...

But it doesn’t work like that. The custom machine they constructed utilises a polar coordinate system, with a rotating bed (the ‘theta’ axis) and four radial axis gantries arranged at 90 ...

STEP 2 - Plot the coordinates (2,3). Remember the x (horizontal) is the first number in the brackets and the y (vertical) is the second number. Each axis is labelled with a scale of numbers ...
