Coordinated Differential Equations

Appendix A Review for students

Here is a list of topics from algebra and calculus that you should make sure you’re familiar with before studying differential equations. To review these topics, click on the links below.
  • Completing the square of a quadratic function (i.e., converting an expression of the form \(ax^2+bx+c\) into one of the form \(a(x-h)^2+k\) ).
  • Solve quadratic equations when factoring does not work (e.g., solve \(x^2 - 4x + 15 = 0\)).
  • Solving \(2 \times 2\) systems of linear equations (e.g., solve \(2x + y = 1, x - 3y = 2\)).
  • Basic derivatives (power rule, product, chain, and quotient rules, trigonometric functions, exponential and logarithmic functions). Also know basic partial derivatives.
  • Basic integration (integrals of power functions, including integral of \(\frac1x\text{,}\) integrals of trigonometric and exponential functions)
  • Integration by u-substitution.
  • Integration by parts.
  • Integration by partial fractions.
