WebJun 24, 2016 · Explanation: Our goal should be to make this mirror the arctangent integral: ∫ 1 u2 +1 du = arctan(u) +C. To get the 1 in the denominator, start by factoring: ∫ 1 x2 +4 dx = ∫ 1 4(x2 4 +1) dx = 1 4∫ 1 x2 4 + 1 dx. Note that we want u2 = x2 4, so we let u = x 2, which implies that du = 1 2dx.

WebMay 21, 2024 · ∫ x 2 /((x-1)(x-2)(x-3)) We need to solve for A, B and C. One way to do this is to pick values for x which will cancel each variable. Put x = 1 in the above equation, we get . ⇒ 1 2 = A(1 – 2)(1 – 3) + B(1 – 1)(1 – 3) + C(1 – 1)(1 – 2) ⇒ 1 = 2A + 0 + 0. ⇒ A = \(\frac{1}{2}\) Now, Put x = 2 in equation (ii), we get WebClick here👆to get an answer to your question ️ Evaluate the integral int 2^3( x^2 + 2x + 5) dx .
