Where it gets hard

The units students slow down on, and what makes each one heavy.

  • Module 1:

    Unit 1: Ordinary Differential Equations

    Solving exact ODEs requires careful application of partial derivatives and integration techniques to find the implicit solution.

  • Module 1:

    Unit 1: Ordinary Differential Equations

    Applying the method of undetermined coefficients involves correctly guessing the form of the particular solution based on the nonhomogeneous term.

  • Module 2:

    Unit 2: Existence and Uniqueness Theorem

    The proof of the existence and uniqueness theorem requires a solid understanding of real analysis concepts and careful application of inequalities.
