Numeric Solver
Consider the equation a=(m2Nm1)/(m2+m1)…g, where the known values
are m2=10 and g=9.8. If you assume that a=1/3 g, find the value of m1.
Steps and keystrokes Display
1. Use O to display the Numeric Solver.
2. Enter the equation.
When you press ¸ or D, the screen lists
the variables used in the equation.
@ j A Á c j M2 | j M1 d e
c j M2 « j M1 d p j G
¸
3. Enter values for each variable, except the
unknown variable m1.
Define m2 and g first. Then define a. (You
must define g before you can define a in
terms of g.) Accept the default for bound.
If a variable has been defined previously, its
value is shown as a default.
@D 10 D D 9.8 C C C j G e 3
4. Move the cursor to the unknown variable
m1.
Optionally, you can enter an initial guess for
m1. Even if you enter a value for all
variables, the Numeric Solver solves for the
variable marked by the cursor.
Press D D
g/3 is evaluated when you
move the cursor off the
line.
5. Solve for the unknown variable.
To check the solution’s accuracy, the left and
right sides of the equation are evaluated
separately. The difference is shown as
left-rt. If the solution is precise, left-rt=0.
Press „
0 marks the calculated
values.
