== Unit Circle Diagram ==
Contains a number of errors. I'm not in a good position (ie. edit SVGs) to correct them. The value for sixty degrees is given as
:<math>\sin \frac\pi3 = \sin 60^\circ = \frac{\sqrt{3}}{2} = \frac{1}{2}</math>
which is not the case. It's correct in the table next to the diagram.

:Sorry, in my understanding it says:
:<math>(\cos,\sin)(\frac{\pi}3) = (\cos,\sin)(60^\circ) = (\frac{1}{2},\frac{\sqrt{3}}{2})</math>,
:which is correct. –[[User:Nomen4Omen|Nomen4Omen]] ([[User talk:Nomen4Omen|talk]]) 15:08, 9 April 2023 (UTC)
:: Um, that is correct. Hmm. I was busy converting between radians and degrees and didn't read the legend carefully enough. Thanks! [[User:Mwasheim|Mwasheim]] ([[User talk:Mwasheim|talk]]) 15:21, 9 April 2023 (UTC)
: as an aside, I wonder if it would help people sitting there with calculators which use radians (ie. all?) to specify that sin 90 is generally sin(rad(90)) on calculators?
