The temperature of a soup is increasing at a rate of r (t)=30e^ {-0.3t} r(t) = 30e−0.3t degrees Celsius per minute (where t t is the time in minutes). At time t=0 t = 0, the temperature of the soup is 23 23 degrees Celsius. And imagine we are asked to find the amount by which the ...

WebJun 9, 2016 · My own example of solving an integral using only substitution and algebraic manipulations. Solve (not really tough, but not simple either): ∫ 0 ∞ d x ( 1 + x) ( π 2 + ln 2 x) Let's introduce a parameter: I ( v) = ∫ 0 ∞ d x ( v + x) ( π 2 + ln 2 x) Let's make a change … WebMar 1, 2024 · Example 4: Solve this definite integral: \int^2_1 {\sqrt {2x+1} dx} ∫ 12 2x+ 1dx.

WebAnswer: As Victor Loh has said in his comment, this question is indeed subjective. But if you ask me, I will propose the following improper integral as a hard problem: I=\int_{0}^{\infty} \cos\left( \frac{x (x^2-\alpha^2)}{x^2-\beta^2} \right) \, \frac{dx}{x^2 + \gamma^2} This integral was subm... WebSo, the answer is, no, you cannot do u-substitution that way. With integration, being close to a standard form is not good enough: you must have an exact match. For example, ∫ (x)∙cos(x²) dx is very easy to integrate but the very similar looking ∫ cos (x²) dx is nightmarishly difficult (getting into something called Fresnel integrals).
