WebA u -sub can be done whenever you have something containing a function (we'll call this g ), and that something is multiplied by the derivative of g. That is, if you have ∫ f ( g ( x)) g ′ ( x) d x, use a u-sub. Integration by parts is whenever you have two functions multiplied together--one that you can integrate, one that you can ... WebDec 9, 2024 · 1 Answer Sorted by: 1 Both your questions can be explained by looking at the graph of y. You'll notice that y is not differentiable at x = 0 so your concern about x / x = 1 doesn't matter because there is no derivative there. You'll notice that for x > 0 the derivative is negative and for x < 0 the derivative is positive.
