Understand
Remember an answer.
Or understand why.
Understand brings together lessons, exercises, and worked corrections for higher education, the Moroccan baccalaureate, and programming. Hints help learners move forward without immediately revealing the answer.

The right answer

the beginning.
This small example follows the public experience: a difficulty, progressive hints, an explained correction. Take a moment to think before opening the next clue.
An excerpt of Understand’s public exercise, presented here. Your progress is not saved.
0? Careful: numerator and denominator both approach zero. That is an indeterminate form.
01A first hint
Set u = arctan t. Then t = tan u. As t approaches 0, what happens to u?
02Change your point of view
The fraction arctan t / t becomes u / tan u. You may recognise the limit of tan u / u.
03Follow the reasoning
arctan is continuous at 0 and arctan 0 = 0, so u approaches 0 with t. For t ≠ 0, arctan t / t = u / tan u.
Since tan u / u approaches 1, its reciprocal u / tan u also approaches 1. By composition:
limt → 0 arctan t / t = 1
One clue, then another. The answer comes with the reasoning.
