Note the following points to ensure correct integration values.
(1) When cyclical functions for integration values become positive or negative for
(2) When minute fluctuations in integration divisions produce large fluctuations in

• Pressing A during calculation of an integral (while the cursor is not shown
on the display) interrupts the calculation.
• Always use radians (Rad Mode) as the angle unit when performing trigono-
metric integrations.
• Factors such as the type of function being used, positive and negative values
within divisions, and the division where integration is being performed can
cause significant error in integration values and erroneous calculation results.
different divisions, perform the calculation for single cycles, or divide between
negative and positive, and then add the results together.
integration values, calculate the integration divisions separately (divide the
large fluctuation areas into smaller divisions), and then add the results
together.
