WebNov 10, 2024 · Integration by Parts Let u = f(x) and v = g(x) be functions with continuous derivatives. Then, the integration-by-parts formula for the integral involving these two functions is: ∫udv = uv − ∫vdu. The advantage of using the integration-by-parts formula is that we can use it to exchange one integral for another, possibly easier, integral. WebDec 20, 2024 · The Integration by Parts formula gives ∫arctanxdx = xarctanx − ∫ x 1 + x2 dx. The integral on the right can be solved by substitution. Taking u = 1 + x2, we get du = 2xdx. The integral then becomes ∫arctanxdx = xarctanx − 1 2∫ 1 u du. The integral on the right evaluates to ln u + C, which becomes ln(1 + x2) + C. Therefore, the answer is how a tower crane works https://wakehamequipment.com
