Algebra System Precautions
7-4 Algebra System Precautions
• If an algebraic operation cannot be performed for some reason, the original expression
remains on the display.
• It may take considerable time to perform an algebraic operation. Failure of a result to
appear immediately does not indicate malfunction of the computer.
•Any expression can be displayed in various different formats. Because of this, you
should not assume that an expression is wrong just because it does not appear as you
expected.
• This calculator performs integration calculations under the assumption that integrals are
always positive, even when the integrals are discontinuous (due to a switch between
positive and negative).
f(x)
F(x): primitive function of f(x)
