| Math Modeling: Solving Differential Equations with TK Solver |
| A procedure function with three arguments is used to represent one or more coupled differential equations. The function inputs, in order, are the derivative matrix name (used internally by the integrator functions only), the dependent variable matrix name, and the name of the independent variable list. As with all input variables in procedure functions, these variable names are local to the function, so you can use whatever names you wish. |

| Math Modeling: Statistics & Curve Fitting |
| Excel is loaded with statistical tools but TK Solver provides a handy collection of its own and can be used as a supplement in several areas. Data can be copied from Excel into TK lists or tables. |

| Math Modeling: String Manipulation and Recursion |
| In this example we show how TK's string functions can be combined to perform important housekeeping tasks necessary in some models. The custom-built function we describe takes advantage of recursion. |

| Math Modeling: Tutorial for Teaching Plotting |
| In TK, you plot with lists, which are equivalent to one-dimensional arrays. A list of y values, for example, can be plotted against a list of x values. Lists can be created by solving equations, by typing in list elements one by one or by importing data files. |

| Roark's Formulas: Superposition Wizard Article |
| The Superposition data entry wizard (SDEW) works with TK Solver allowing information to be simply entered in as few steps as possible. It consists of a series of screens that allow data to be both entered and selected from pull down menus. Beam and plate solutions become simple and quick to use. |
