Plot view  You can plot only one equation at a time in the Solve app, so make sure that only 

one equation is selected in Symbolic view. To display Plot view, press 

P

. The left side and the 

right side of the selected equation are plotted as separate graphs. The variable that was 

highlighted in Numeric view is taken as the independent variable.
The Plot View menu items, and the Plot Setup view, are the same as in the Function app. (See 

page 19.) However, there is no 

 functionality in the Solve app.

The HP Prime has three Solver apps, each designed to solve problems of a specific type: a Finance app, a Linear Solver app, and 

a Triangle Solver app. The Finance app solves time-value-of-money (TVM) and amortization problems, the Linear Solver finds 

solutions to systems of linear equations, and the Triangle Solver finds measures of angles and lengths of sides in problems 

involving triangles.

The Finance App solves time-value-of-money (TVM) and amortization problems. To open the 

Finance app, press 

I

 and select 

. The Finance app has two pages: one for TVM 

problems and the other for amortization. The amortization page uses values from the TVM page.
The TVM page enables you solve TVM problems. You enter as much data as you have and then 

highlight a variable whose value you want to calculate. The fields are:

•

: total number of periods or payments

•

: the nominal annual interest rate

•

: present value at the start of the cash flow

•

: the number of payments made in a year

•

: the payment due per period
