<p>neha this is single variable calculus; although they wouldn't really ask you something like this in 18.01 since this calculation can't be integrated directly (and although I haven't taken it I'm sure questions are more than just simple integrals anyway)</p>
<p>If you're solving an equation and get to int (1/ln(x)), than the answer is just int(1/ln(x)); that's in simplest form</p>
