Differential Calculations

Press
To perform a differential calculation, you have to input the
expression in the form of:
• The differential expression must contain the variable x.
• "a" is the differential coefficient.
• " x" is the change interval of x (calculation precision).
Example: To determine the derivative at point x = 10,
the function f(x) = sin(3x + 30).
