Introduction
I purchased My TI-nspire CX II CAS, Calculator in early 2021 for an Engineering maths subject and Mechanical Masters. Here you will find a summary of the useful things I have learnt.
Layout and Buttons
Getting Around
Swap Deg / Rad
Use the trackpad to click on the Rad or Deg text in the top right corner.
Functions
Solve
Domain
Domain(formula,variable) – Finds the posible values of a variable in a function. example, Domain(5/(3(cos(9x)-3)),x) –> Enter
Rational Fractions to Partial Fractions
Expand and Factor
Factorising Polynomials
polyRoots(Poly, Var)
Limits
Vectors
dotP([ ],[ ])
crossP([ ],[ ])
Matrices
Row Operations
add row row(), rowAdd(Matrix,rindex1,rindex2)
move a row —> rowSwap(Matrix, rIndex1, rIndex2)
multiply row –> mRow(Expr, Matrix, Index)
Add and Multiply a row. —> mRowAdd(Expr, Matrix, Index1, Index2)
