HL syllabus content: first order differential equations; numerical solution of \(\frac{{{\rm{d}}y}}{{{\rm{d}}x}} = f\left( {x,y} \right)\) using Euler’s method; by separation of variables; homogeneous differential equations; solutions using the integrating factor method (HL only)go to teaching materials ↴The HL syllabus content on differential equations can be a challenge to teach and a challenge for students to fully understand. Certainly, differential equations...
