Dividing the numbers $0, 1, 2, 3, 4$ by $4$ and taking square roots gives the values of—

a $\cos 0^\circ, \cos 30^\circ, \cos 45^\circ, \cos 60^\circ, \cos 90^\circ$
b $\sin 0^\circ, \sin 30^\circ, \sin 45^\circ, \sin 60^\circ, \sin 90^\circ$
c $\tan$ of the same angles
d $\cot$ of the same angles

Taking $\sqrt{0/4},\sqrt{1/4},\sqrt{2/4},\sqrt{3/4},\sqrt{4/4}$ yields $0,\tfrac12,\tfrac{1}{\sqrt2},\tfrac{\sqrt3}{2},1$ , which are exactly the sine values for $0^\circ,30^\circ,45^\circ,60^\circ,90^\circ$ . This is the standard mnemonic for the sine table.
