Research has found that rising temperatures in the Arctic are weakening weather systems that normally trap the cold around ...

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 ...

Researchers have discovered that a single molecule, Wnt3, coordinates a two-step process of cell polarity orientation that ...

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 ...

A scope for use with the Vixen Star Tracker to help gain more accurate polar alignment. It has Time graduation circle in 10 in increments, a meridian offset scale in 5 degree increments and a 6x20 ...
