Today& #39;s #dailymaths CHALLENGE PROBLEM. Problems are taken from the Mathematics 2020 calendar. Each day& #39;s problem (w/previous day& #39;s solution) is posted no later than 9am Eastern. Guest mathematicians welcome; DM if you, your kid, or your students are interested!

Yesterday’s problem and solution. This one is by me, with both a visual representation of what integration problems are really asking and a step by step explanation of this one.

Bonus! Isabel Hebert, 12 year old daughter of @marina_khs, used the hints in yesterday’s thread and solved her first calculus problem!! Hints are posted daily by @pgeerkens and sometimes others in the #dailymaths threads. Way to go Isabel!!! https://abs.twimg.com/emoji/v2/... draggable="false" alt="😃" title="Smiling face with open mouth" aria-label="Emoji: Smiling face with open mouth">https://abs.twimg.com/emoji/v2/... draggable="false" alt="👍🏼" title="Thumbs up (medium light skin tone)" aria-label="Emoji: Thumbs up (medium light skin tone)">https://abs.twimg.com/emoji/v2/... draggable="false" alt="👍🏼" title="Thumbs up (medium light skin tone)" aria-label="Emoji: Thumbs up (medium light skin tone)">https://abs.twimg.com/emoji/v2/... draggable="false" alt="👍🏼" title="Thumbs up (medium light skin tone)" aria-label="Emoji: Thumbs up (medium light skin tone)">
