Question

How do you find the exact value of `arcsin(1/3)`?

Answer 1

You get my answer, from my explanation.

Explanation:

In general, any value is transcendental. Yet, define units like

second, ounce, foot, dollar, ... and express values, rounded to

nearest unit .

In the values of arcsin that `in [ - pi/2, pi/2 ]`, a particular value,

say 0.1 rad = (0.1/pi ) 180^o = 5.729577951...^o is transcendental.

For that matter,

arcsin ( 1/3) = 19.47122063...^o = 0.339836836909... rad.

In my opinion, all irrational values are transcendental that defy

rational form ( integer )/( integer ).
