The sin is y/r.  R = 1

anonymous · Answer

since this is an approximation, then sin1 = the y-coordinate of that point on the red "1"....

anonymous · Answer

yw...
in fact, the definition of sine IS the y-coordinate of a point on the unit circle...

@dpaInc how do i find tan 0.8?

anonymous · Answer

are we still approximating?
$\huge tan(0.8)=\frac{sin(0.8)}{cos(0.8)} $

tabithax3 · Answer

@dpaInc we are by approximating by using the graph
