Note the following points to ensure correct integration values.

(1) When cyclical functions for integration values become positive or negative for

different divisions, perform the calculation for single cycles, or divide between

negative and positive, and then add the results together.

(2) When minute fluctuations in integration divisions produce large fluctuations in

integration values, calculate the integration divisions separately (divide the large

fluctuation areas into smaller divisions), and then add the results together.
