• Specify a tolerance (
solution that satisfies the tolerance value can be obtained.
• The rules that apply for linear differential also apply when using a quadratic differential
calculation for the graph formula (see page 2-24).
• Inaccurate results and errors can be caused by the following:
- discontinuous points in
- extreme changes in
- inclusion of the local maximum point and local minimum point in
- inclusion of the inflection point in
- inclusion of undifferentiable points in
- differential calculation results approaching zero
• You can interrupt an ongoing quadratic differential calculation by pressing the
• Always use radians (Rad mode) as the angle unit when performing trigonometric quadratic
differentials.
• You cannot use a differential, quadratic differential, integration, , maximum/minimum value,
Solve, RndFix or log
term.
• With quadratic differential calculation, calculation precision is up to five digits for the
mantissa.
• In the Math input/output mode, the tolerance value is fixed at 1
