Double Integrals

Knowledge Kind on Instagram: "Integration by parts is a fundamental technique in calculus used to find the integral of a product of functions. It is essentially the reverse process of the product rule for differentiation. This animation illustrates the formula geometrically by representing the product of two functions, eq u and v, as the area of a rectangle. As these variables change, the total change in the area of the rectangle can be split into two distinct regions: one representing the integ
