The ultimate integration technique: Guessing
@carultch10 ай бұрын
That's called integration by differentiating the Ansatz. You guess the form of the integral result, with undetermined coefficients, then differentiate, and then match coefficients to the original integrand.

@carultch10 ай бұрын
@@FirstnameLastname-bx4zk Similar to it, yes. In a way, it is a solution to a diffEQ, where dy/dx = the given integrand. Here's an example. Consider: Integral (3*x + 4)/sqrt(x + 1) dx Assume the solution has the form: (A*x + B)*sqrt(x + 1) Why? Because we know the net exponent on each x-term, must increase by 1, due to the process of integration. Had sqrt(x) been the radical term instead, it'd be an application of the power rule. This is equivalent to the radical expression moving to the numerator, and a linear expression multiplied out in front. Take the derivative, to get: (3*A*x + 2*A + B)/(2*sqrt(x + 1)) This tells us that: 3*A/2 = 3 (2*A + B)/2 = 4 Solution: A = 2, B = 4 Thus the solution is: (2*x + 4)*sqrt(x + 1) + C This method doesn't always work for integrals of this form, as they can also have inverse trig or logs as part of the solution. If that is the case, you'll have a degenerate system of equations when trying to solve for A & B.

Trig sub: most fun Int by parts: easy to set up with DI method u-sub; pretty goated and is pretty easy to understand Power rule: simple, however limited to simple polynomials. Partial fractions: the worst of all. Although it’s not hard a simple problem will take a long time because the fractions take a while to set up. But once it’s set up, it’s pretty easy to integrate. Improper integrals: also not that bad, just make sure you are good at taking limits.
