Question

find sin(arccsc(20)),where arccsc(theta) is the inverse of csc(theta).

Answer 1

So let \[\theta = arc\csc(20)\]We have \[\csc(\theta)=\frac{20}{1}\]Or in other words:\[\sin(\theta)=\frac{1}{20}\]Hmmmm.

Answer 2

What happens when we replace \(\theta\) back with \(arc\csc(20)\)...

Answer 3

@krypton Making sense?
