Solve Calculations

The solution of the function is approximated using Newton's method.

u u u u u Newton's method

This method is based on the assumption

that

expression within a very narrow range.

First, a starting value (predicted value)

given. Using this starting value as a base,

approximate value

the left side and right side calculation

results are compared. Next, approximate

value

calculate the next approximate value

This procedure is repeated until the

difference between the left side and right

side calculated values is less than some

minute value.

• An error occurs if you input more than one equals sign.

• "Lft" and "Rgt" indicate the left and right sides that are calculated using the

approximate value. The closer the difference between these two values is to

zero, the greater the accuracy of the result.
