Calculation of indirect errors description

The application calculates the INDIRECT ERROR of the value BASED on the entered FORMULA, values and ERRORS of the VARIABLES on which this function depends.

Working with the APPLICATION:
entering a FORMULA implies a set of mathematical operations on variables.
SUPPORTED MAT. OPERATIONS:
+, -,*,/; sin(x), cos(x), tan (x);
exp ( x) - raising the number " e " to the power of x, pi - the number of PI
entering VARIABLES implies entering
1. the symbol (which was used to indicate this variable in the formula),
2. the numerical value of the variable (the value of the best estimate of the variable value),
3. the numerical value of the error (the error of the best estimate of the variable value).

after CLICKING the button, the result is provided at the bottom of the screen.
The first line shows the FORMULA and the NUMERICAL RESULT of calculating the value of the DESIRED VALUE.
The second line shows the FORMULA and the NUMERICAL RESULT of calculating the ERROR value of the desired value.
