Integration by parts is one of the most powerful but often tricky methods in calculus. It’s based on the product rule of differentiation and helps in solving complex integrals where functions are multiplied together — like x⋅exx \cdot e^xx⋅ex, x⋅ln(x)x \cdot \ln(x)x⋅ln(x), or x⋅sin(x)x \cdot \sin(x)x⋅sin(x). However, doing these manually can take time, especially when…
