Today's #dailymaths CHALLENGE PROBLEM. Problems are taken from the Mathematics 2020 calendar. Each day's problem (w/previous day'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!!!
