Typo? A mix-up of 2 problems?
\n" ); document.write( "The part that says
\n" ); document.write( "f''(x)= 2x +(1/root(3. x)
\n" ); document.write( "does not agree with the rest.
\n" ); document.write( "If $\"f%28x%29\"$ is a function whose first derivative is the constant 2,
\n" ); document.write( "as in $\"%22f+%27+%28++x+%29+=%22\"$ $\"2\"$ ,
\n" ); document.write( "then its second derivative is zero, $\"%22f+%27+%27+%28++x+%29+=%22\"$ $\"0\"$ ,
\n" ); document.write( "and $\"f%28x%29=2x%2BC\"$ for some constant $\"C\"$ .
\n" ); document.write( "If also $\"f%281%29=2\"$ then $\"2%2A1%2BC=3\"$ , so $\"C=1\"$ and $\"f%28x%29=2x%2B1\"$ . \n" ); document.write( "
