What this AI HL coupled and second-order differential equations worksheet covers

HL calculus: systems of coupled linear differential equations, phase portraits, eigenvalue solutions and second-order equations by substitution. The questions follow the order of the AI HL syllabus for Topic 5 (Calculus) and are graded in three bands — routine practice, exam-standard, and the harder multi-step questions that separate a 6 from a 7.

Writing a coupled system in matrix form
Eigenvalues and eigenvectors to find the general solution
Classifying equilibrium points and sketching phase portraits
Reducing a second-order equation to a coupled first-order system; Euler's method
Exam tip for this topic. Sign of the eigenvalues decides the phase portrait — write the classification table before sketching.

How to use it

  1. Do the first band without the AI HL formula booklet, then check which formulas you had to look up — those are the ones to memorise.
  2. Time the second band at roughly 1.2 minutes per mark, the pace of Paper 1 and Paper 2.
  3. Mark the third band against the solutions and rewrite every question you lost marks on from a blank page.
