sinL=6/7

Question

L(alfa)=?

Answer 1

If sin(α)=x, then
α
=sin^-1x (arcsin(x))

If you have to evaluate the value of sin^-1(6/7) on the calculator, use the key combination [inv][sin], or [2nd][sin]. This should work on most calculators.
I get
sin^-1(6/7)=1 radian or 59 degrees, approximately.

Answer 2

2X(SIN
