Arc Length Option

Press to view the calculus menu, then to select arc length.

The syntax is: arc( expression,variable ,startValue,endValue )

The maximum option finds the length along the curve expression as variable ranges from startValue to endValue.

Note: The arc length is found by calculating the integral .

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 tol. A smaller value yields a more accurate integral but takes longer to compute. It can be changed in the tolerance editor available by pressing . Its value is typically about 0.001.
