Create a function whose derivate is:

Calculation of $sinh(ln(x+\sqrt{x^2+1}) $ => $x = 0$ 
Derivate of $ ln(x+\sqrt{x^2+1})$ => $\tfrac{1}{\sqrt{x^2+1} } $ 
arcsin^-1(x) = $\tfrac{1}{\sqrt{x^2 +1 } } $ 

Use the previous information:

Let F be a continuously differentiable function everywhere, and let F be its derivative. Determine a function whose derivative is

$\tfrac{F'(x)}{\sqrt{1+F(x)^2} } $
$\tfrac{F'(2x+3)}{\sqrt{1+F(2x+3)^2} } $
