## Trigonometry (10th Edition)

$y$$_{1} = \sin y$$_{2}$ = $\tan$
We must verify the values in each column to each function. $\sin$ 0$^{\circ}$ = 0 $\sin$ 15$^{\circ}$ = .25882 $\sin$ 30$^{\circ}$ = $\frac{1}{2}$ = 0.5 $\sin$ 45$^{\circ}$ = $\frac{\sqrt2}{2}$ = 0.70711 $\sin$ 60$^{\circ}$ = $\frac{\sqrt3}{2}$ = 0.86603 $\sin$ 75$^{\circ}$ = $\frac{\sqrt3 + 2}{2\sqrt2}$ = 0.96593 $\sin$ 90$^{\circ}$ = 1 $\tan$ 0$^{\circ}$ = 0 $\tan$ 15$^{\circ}$ = .26795 $\tan$ 30$^{\circ}$ = $\frac{1}{\sqrt3}$ = .57735 $\tan$ 45$^{\circ}$ = 1 $\tan$ 60$^{\circ}$ = $\sqrt3$ = 1.7321 $\tan$ 75$^{\circ}$ = 3.7321 $\tan$ 90$^{\circ}$ = undefined
