Chapter 0 A short mathematical review A basic understanding of calculus is required to undertake a study of differential equations. This zero chapter presents a short review. analysis considers functions of one, two, or n variables, studying their properties as well as those of their derivatives; the theories of differential and integral equations aim at solving equations in which the unknowns are functions; functional analysis works with spaces made 1.1 First Order Equations Though MATLAB is primarily a numerics package, it can certainly solve straightforward diﬀerential equations symbolically.1 Suppose, for example, that we want to solve the ﬁrst order diﬀerential equation y′(x) = xy. (1.1) We can use MATLAB’s built-in dsolve(). The input and output for solving this problem in

Di erential Equations contain the derivatives of (possibly) unknown functions. Represent how a function is changing. We work with rst-order di erential equations - only include rst derivatives Generally real-world di erential equations are not directly solvable. Often we use numerical approximations to get an idea of the unknown function’s shape.

Systems of Equations—Quick Reference Graphing Systems of Equations Two linear equations form a system of equations. You can solve a system of equations using one of three methods: 1. Graphing 2. Substitution Method 3. Linear Combinations Method Substitution Method Solve the following system of equations: x – 2y = -10 y= 3x x – 2y = -10

Solving Radical Equations . Follow the following four steps to solve radical equations. 1. Isolate the radical expression. 2. Square both sides of the equation: If x = y then x 2 = y 2. 3. Once the radical is removed, solve for the unknown. 4. Check all answers.
