be differentiated. Thus, to calculate the derivative d(sin(r),r), use, in ALG mode:
‚¿~„r„ÜS~„r`
In RPN mode, this expression must be enclosed in quotes before entering it into
the stack. The result in ALG mode is:
In the Equation Writer, when you press ‚¿, the calculator provides the
following expression:
The insert cursor () will be located right at the denominator awaiting for the
user to enter an independent variable, say, s: ~„s. Then, press the right-
arrow key (™) to move to the placeholder between parentheses:
Next, enter the function to be differentiated, say, s*ln(s):
