Question

please explain y=(11/3)cos^-1(5-2x)

Answer 1

I assume you mean:
\[y=\frac{11cos^{-1}(5-2x)}{3}\]
\[\text{ Where }cos^{-1}\text{ is the inverse cosine function}\]

Answer 2

yes that is correct. I know \[\cos^1=-1/\sqrt{1-(5-2x^2) but don't know what to do after that

Answer 3

yes that is correct. I know \[\cos^1=-1/\sqrt{1-(5-2x^2) but don't know what to do after that
