Arc Length Option
to access the arc length option
which finds the length of a curve between two values.
Next, enter an expression, the variable, a start value, and an end value
separated by commas. For example, to find the length of the curve y = x2
between x = 2 and x = 3 inclusive, enter
Note: The error is described as tolerance, tol. The value of
tol is used to determine how accurate to calculate
this integral. The TI tries to keep the absolute error under
A smaller value yields a more accurate integral but takes longer to compute.
It can be changed in the tolerance editor available by pressing
value is typically about 0.001.
