Question

Can someone help me figure out how to do this >.<

Answer 2

you are looking for \(\tan(\arcsin(x))\)

Answer 3

there is a picture of an angle whose sine is \(x\)
you need the adjacent side, which by pythagoras is \(\sqrt{1-x^2}\)

Answer 4

ans so
\[\tan(\arcsin(x))=\frac{x}{\sqrt{1-x^2}}\]
