Trigonometric Substitution
🕑 Added 2023-01-03 19:23:13 +0000 UTCThis calculus video tutorial provides a basic introduction into trigonometric substitution. It explains when to substitute x with sin, cos, or sec. It also explains how to perform a change of variables using u-substitution integration techniques and how to use right triangle trigonometry with sohcahtoa to convert back from angles in the form of theta to an x variable. There's plenty of examples and practice problems in this lesson.

Great video, why did you integrate for a second time though at 57:40?
