Primes

LATEX provides the control word \prime (′) for priming symbols. Note that it is not automatically at the superscript height, so that to get f you would have to type

0.1

$f^\prime$ .
To make lighter work of this, LATEX will interpret a right-quote character as a prime if used in maths mode. Thus we can type

0.1

$f'(g(x)) g'(x) h''(x)$
in order to get

f'(g(x))g'(x)h''(x)    .
