## krypton Group Title find sin(arccsc(20)),where arccsc(theta) is the inverse of csc(theta). 2 years ago 2 years ago

1. wio

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

2. wio

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

@krypton Making sense?

4. krypton

hm.. dont really know the topic,is there any rules for it?
