Ive tried to enter the calculation in a calculator
asin(35.4)(sin(51)/31.2)
why do i get an error??
Since the trigonometric functions are based on a unit circle,
it can't tell you what the arcsin of 35.4 is.
You can only take the arcsin of a value between -1 and 1 (including -1 and 1).
I would not say that trigonometric functions are based on the unit circle but it is certainly true that
asin(x) only is defined (has a value) for
\(-1\le x\le1\)
