BTW, no calculator is needed to check this, since 1,234,567,800 is divisible by 5 (ends with 0), 8 (last 3 digits make 800, which is divisible by 8), and 9 (sum of its digits is 45, which divisible by 9), so it's a multiple of 360. Therefore sin[1,234,567,890°]=sin[360°×n+90°]=1.
Who did the maths is going to Hell, because it's sin.
sin x = x
Not a great fact tbh. Any student trained in elementary trigonometry will be able to guess this
Yeah but the fact is that it's 1234567890, which is way more interesting
And sin(9,876,543,210°)=1, since 9,876,543,210=27,434,842×360+90.
Aquesta t´agradarà, @miquel_siquier ! 
PD: Aquest perfil de @Twitter se diu així en honor a Fermat, que va ser un dels grans. No és estrany que mirant al cel també n´hi hagi més "Fermats": un asteroide, un cràter lunar...
Fancy!
