How do you find the exact value of #arcsin(sin(2))#?
The exact value of
Whenever we take the arcsin of sin, or the arccos of cos, or the inverse of any trig function, they always cancel each other out. So
The reason for this is because to find the arcsin of a given number, for instance,
So with this problem, instead of
As an equation with our desired answer being n, that looks like
This also works no matter order we're taking
