8. Press 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 screen, allowing you to check the error range. � This method finds an approximate value of the solution, so that the difference between right and left side of the equation is 0. � The value obtained by this method may include an error. As the difference between right and left sides small, a close to real value is obtained. (If the difference is large, the error is also large.) Therefore, when difference between the right and left sides is large, a value close to the real value is not obtained. (Press to return to the variable input screen.) 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.

SOLVER FUNCTION
� If this occurs, change the STEP and START values and recalculate the solution. � Additionally, if a difference between the right and left sides exists, recalculate with
¬
(2) Graph method
� In graph method, solution is found by plotting 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.
