5. Enter the seed value in the X field:
2
The calculator will provide one solution (if there is one) and
you will not be alerted if there are multiple solutions. Vary the
seed values to find other potential solutions.
6. Select the variables you want solutions for. In this example
we want to find values for both X and Y, so make sure that
both variables are selected.
Note too that if you have more than two variables, you can
enter seed values for more than one of them.
7. Tap
to find a solution
near X = 2 that satisfies
each selected equation.
Solutions, if found, are
displayed beside each
selected variable.
You cannot plot equations if more than one is selected in
Symbolic view.
The HP Prime will not alert you to the existence of multiple
solutions. If you suspect that another solution exists close to a
particular value, repeat the exercise using that value as a seed.
(In the example just discussed, you will find another solution if you
enter –3 as the seed value for X.)
In some situations, the Solve app will use a random number seed
in its search for a solution. This means that is it not always
predictable which seed will lead to which solution when there are
multiple solutions.
When you are solving a single equation, the
appears on the menu after you tap
