I speak strictly for myself. When integrating \int \left[ \sec^3x - \sec x \,\right] dx Surely you know you can separate the terms into \int \sec^3x \,dx - \int \sec x \,dx Now you should memorized the integral of secant x, so that's out of the way. You could also memorize the...

I would like to know.

For anyone who was wondering, the hashtag just meant "negative". Thank you dipole.

During a physics competition, I came across this question. My work was \begin{align*}\Delta S &= \frac{Q}{T} \\ \Delta S &= \frac{1.25 \times 10^3 \, \mathrm{J}}{348 \, \mathrm{K}} \\ \Delta S &= 3.59 \,\,\mathrm{\left( J/K\right )} \end{align*} but I was stuck in between two answer choices...
