Calculus Integration Techniques in 20 Minutes

Показать описание
This video is dedicated to my Differential Equations students, who have performed amazingly well to get to this point. They have all taken Calculus 1 and Calculus 2 during a worldwide pandemic, and did well enough to make it to ODEs.

Though, they might be a bit worse for wear, and this video does a snappy review of all of Calculus 2's integration techniques in 20 minutes. Or at least most of the relevant ones. This includes U substitution, Trigonometric Substitution, Integration By Parts (including solving for the integral), and Partial Fraction Decompositions. Each technique is accompanied by an example.

If you want a quick refresher, this video is for you!

For the Integration By parts question for the integral of sinte^2t dt, isn't it supposed to be NEGATIVE 1/4 (integral) of sinte^2t dt? There are 3 negative signs for that term which would make it negative in the end.

Awww, the "proud of you" section made me finally give myself a pat on the back for continuing my math studies. I really love this channel; your numerical analysis series is excellent too.

there is one more technique! (related to our research group !)
