1. Solve the equation x 2 ì 2x ì 6=2
with respect to x where x is
greater than zero.
The “with” (I) operator provides
domain constraint.

Finding the Derivative of
Functions
1. Find the derivative of
(x ì y) 3 /(x+y) 2 with respect to x .
This example illustrates using the
calculus differentiation function and
how the function is displayed in
“pretty print” in the history area.

Finding the Integral of
Functions
1. Find the integral of x ù sin(x) with
respect to x .
This example illustrates using the
calculus integration function.
