How would you write the following as an algebraic expression:
cos(sin^-1 12x)
I know that I need to use principles of a right triangle and can do similar problems such as cos(sin^-1 (4/x) where x is the hypot. and 4 is the y value. The rest can be figured out from there but the 12x is tripping me up.

You can write $12x$ as $\frac{12x}{1}$.

I had tried that but it didn't end up working. I've figured it now though!
