N, I%, PV, PMT, FV
Ú, æ,
PV, PMT, and FV are the five TVM variables. They represent the elements of common
financial transactions, as described in the table above. æ
is an annual interest rate that is
converted to a per-period rate based on the values of
P/Y and C/Y.
P/Y and C/Y
P/Y is the number of payment periods per year in a financial transaction.
C/Y is the number of compounding periods per year in the same transaction.
When you store a value to
P/Y, the value for C/Y automatically changes to the same value. To
store a unique value to
C/Y, you must store the value to C/Y after you have stored a value to P/Y.
The EasyData™ Application
The Vernier EasyData™ application by Vernier Software & Technology allows you to view and
analyze real-world data when the TI-84 Plus is connected to data collection devices such as Texas
Instruments CBR 2é, CBL 2é, Vernier LabProê, Vernier USB sensors, Vernier Go!éMotion, or
Vernier Motion Detector Unit. The TI-84 Plus comes with the EasyData™ App already installed.
Note: The application will only work with Vernier auto-ID sensors when using CBL 2é and
Vernier
LabProê.
The EasyData™ App will autolaunch on your TI-84 Plus if you plug in a USB sensor such as the
CBR 2é or Vernier USB Temperature sensor.
