\frac{d}{d x} [\frac{x ^{2} + 5}{5 x + 5}]

Too easy? This one too.

difficulty 15double XP

Evaluate \iint_{R} \frac{1}{x ^{2} + y ^{2}} d A, where R = {(r, θ) : 2 \leq r \leq 3, 0 \leq θ \leq \frac{3 π}{2}}

Same for everyone, every day. This one needs an account (free), and you can take it without doing the Daily first.

No timer, no strikes, no mercy. The XP drops with every wrong answer though, so first try is the only try that really counts.
