Partial Fraction Decomposition (pdf)
Explains and demonstrates how to perform partial fraction decomposition using TINspire CAS functions.

Complex Numbers with TINspire (pdf)
Explains and describes how to perform arithmetic and algebraic operations with complex numbers in both
rectangular and polar form using TINspire functions. Examples include graphing, adding, subtracting,
multiplying and dividing complex numbers. Examples of raising complex numbers to powers and finding
roots of complex numbers based on De Moivre's Theorem are also presented.

Calculating Partial Derivatives (pdf)
Calculating Partial Derivatives (tns)
Explains and demonstrates how to find first and second partial derivatives with simple TINspire CAS functions.

Newton's Method with TINspire (pdf)
Code and examples for Newton's Method (tns)
Discusses Newton's Method, shows how to implement it with the Program Editor, and demonstrates how to
use the method to find roots of functions, find points where functions intersect, and find critical points.

Vector Fields and Vector Field Graphs (pdf)
Code and examples for Graphing Vector Fields (tns)
Discusses vectors, vector fields, and graphing vector fields with TINspire code and a Lua script. Presents
examples of calculating and graphing gradient fields, divergence, and curl. The TINspire document requires
TINspire CAS.

Limits, Continuity, and Limit Demonstrations (pdf)
Finite Limit at a Finite Point (tns) 
Demonstrates the relation between epsilon and delta in the epsilondelta definition of limit.
Finite Limit at a Finite Point 2 (tns) 
Demonstrates the value of a function approaching a finite limit as x approaches a finite point.
Finite Limit at Infinity (tns) 
Demonstrates the value of a function approaching a finite limit as x approaches infinity.
Infinite Limit at a Finite Point (tns) 
Demonstrates the value of a function approaching infinity as x approaches a finite point.
Infinite Limit at Infinity (tns) 
Demonstrates the value of a function approaching infinity as x approaches infinity.
Describes, discusses, and provides examples of definitions of limits of functions, continuity of functions, and
the interactive graphs that demonstrate limit definitions. These documents can
be opened and used with both nonCAS and CAS versions of TINspire.

Integration by Parts with the DI Method (pdf)
Examples for Integration by Parts with the DI Method (tns)
Discusses integration by parts in general, presents general examples of integration by parts, then describes
integration by parts with the DI (Tabular) method. Describes how to implement the DI Method in a Lists and
Spreadsheet Page to automate integration by parts, and presents examples of the technique. The TINspire
document requires TINspire CAS.
