• A "Time Out" error occurs when an integration calculation ends
without the ending condition being fulfilled.
• When performing an integration calculation involving trigonometric
functions, specify Rad as the calculator's default angle unit.

• There may be large error in obtained integration values and errors
may occur due to the type of function being integrated, the presence
of positive and negative values in the integration interval, or the
interval.
• Pressing A will interrupt an ongoing integration calculation.
