SOLVER FUNCTION
8. Press
Ï
to find the solution.
As a result, I = 0.084471771 ( 8.45%) is obtained.
Approximate values of the right (RIGHT=) and left
(LEFT=) sides and the difference (L–R =) will appear
on the screen, allowing you to check the error range.
• This method finds an approximate value of the solution, so that the difference
between the right side and left side of the equation is 0.
• The value obtained by this method may include an error. As the difference between
the right and left sides is small, a value close to the real value is obtained. (If the
difference is large, the error is also large.)
Therefore, when the difference between the right and left sides is large, a value
close to the real value is not obtained.
• If this occurs, change the STEP and START values and recalculate the solution.
(Press
¬
to return to the variable input screen.)
• Additionally, if a difference between the right and left sides exists, recalculate with
the obtained value used as the START value to obtain a value closer to the real
value.
• In above example, even if you had not set the Newton method for analysis, the
calculation will be performed in the same manner as described in the equation
method. That is, first the equation method attempts to find the solution. If the solution
cannot be obtained, the method is automatically switched to the Newton method and
the START and STEP value input screen will appear. Inputting numeric values
automatically changes the analysis method to the Newton method.
(2) Graph method
• In the graph method, the solution is found by plotting the right and left sides of the
equation to get the intersection.
• Drawing the graph allows you to understand whether multiple solutions exist,
whether the solution is an inconsequential line or asymptotical line, as well as its
upper and lower limits.
