Furthermore, with

We want to find

You've probably done this kind of problem many times by now.

Use your favorite method -- draw a triangle, or a unit circle, or an angle in standard position, or skip the picture and use

All of the above is really explanation of our thought process.

All we really need to write is something like:

Let

And

So, putting it all together we get:

Evaluate $\mathrm{arcsin}\left(\frac{3}{5}\right)$ .

$\mathrm{sin}(2\cdot 0.6435011)$

Multiply 2 by 0.6435011

$\mathrm{sin}\left(1.28700221\right)$

The result can be shown in multiple forms.

Exact Form:

$\mathrm{sin}\left(2\left(\mathrm{arcsin}\left(\frac{3}{5}\right)\right)\right)$

Decimal Form: 0.96
