Solve differential equations using the integrating factor method for IB Analysis & Approaches HL

n this video, I show the integrating factor method step by step, including: • writing the differential equation in the form dy/dx + P(x)y = Q(x) • identifying P(x) • finding the integrating factor • using the product rule to recognise the derivative of a product • integrating the resulting equation • using an initial condition to find the particular solution • integration by parts within an integrating factor problem 📘 FREE INTRODUCTORY RESOURCE Follow the method and worked example here: https://drive.google.com/file/d/16vnx... This video is part of my free IB Mathematics: Analysis & Approaches HL Differential Equations series. Topics in the series include: • Separation of variables • Homogeneous differential equations • Integrating factors • Euler’s numerical approximation Subscribe for more original free AAHL practice, mock papers and fully worked solutions.
