Reminder that radians are gay, so is pi. Use degrees like a rational being and also use floating point numbers. Square root notation can fuck off.

But radians are unitless and don't have any rounding errors

for me it's
$sin(0^{\circ}) = \frac{0^{1/2}}{2}\\ sin(30^{\circ}) = \frac{1^{1/2}}{2}\\ sin(45^{\circ}) = \frac{2^{1/2}}{2}\\ sin(60^{\circ}) = \frac{3^{1/2}}{2}\\ sin(90^{\circ}) = \frac{4^{1/2}}{2}\\ $

cool, but it doesn't work for 15

sin 15° = (?6- ?2)/2

What do you mean it doesn't? Sqrt(6) - sqrt(2) = sqrt(4)

Now switch the order of 0 to 90 but keep the fractions on the right and you get it for cosine.

Isn't this a mathematical coincidence and there's no real explanation for it

Retard. A radian is a unit, just one without dimension
