NettetLearn how to solve integrals by partial fraction expansion problems step by step online. Find the integral int((4x)/(x^3-x^2-x+1))dx. Take out the constant 4 from the integral. We can factor the polynomial x^3-x^2-x+1 using the rational root theorem, which guarantees that for a polynomial of the form a_nx^n+a_{n-1}x^{n-1}+\\dots+a_0 there is a rational … Nettet>> Integration by Parts >> Prove that: int√ (a^2- x^2)dx = x2√ (a^2 Question Prove that: ∫a 2−x 2dx= 2xa 2−x 2+ 2a 2sin −1(ax)+c Hard Solution Verified by Toppr Let I=∫a 2−x 2dx =∫ a 2−x 2⋅1dx On integrating by parts, we get I= a 2−x 2∫1dx−∫[dxd ( a 2−x 2)∫1dx]dx =x a 2−x 2−∫2 a 2−x 2−2x x⋅dx =x a 2−x 2−∫ a 2−x 2(a 2−x 2)−a 2dx
