Показать описание
u-substitution is an immensely powerful strategy in calculus, for A-Level and beyond. With integration being such a mammoth topic to master, and u-subs being part of that mastery, I figured it couldn't hurt to introduce it earlier, and to give this subject a little more attention.

This video introduces the concept of u-substitution, showing why it works in relation to integrating [f(a𝑥 +b)]ⁿ or k[f(a𝑥 +b)]ⁿ. Please make sure you have finished Year 13 differentiation before watching.
