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 ...

We report that ZTF J0112+5827 is a newly identified polar," the researchers wrote. By analyzing the light curve of ZTF J0112+5827, Lin's team identified peculiar double spikes and found that the ...

So how could an old school draftsman figure out the area of complex shapes? [Chris Staecker] introduces us to the polar planimeter, a measuring tool created specifically for the purpose and ...

Scientists confirm ZTF J0112+5827 as a polar cataclysmic variable, with strong magnetic fields and no accretion disk ...
