Inequalities [in RUN-MAT]
Finding regions that satisfy constraints as used in linear programming.
Algebraic substitution – numeric [in RUN-MAT]
This activity shows how the calculator can be used to substitute numerical values into algebraic expressions.
Algebraic substitution is where an independent numerical variable, usually x, is substituted into an equation for a
dependent variable, usually y.
To have ‘?’ and ‘:’ statements:
You are able to trace the ‘different parts’ of a Piecewise Function using [SHIFT] [F1], then the
replay arrows.
Make sure that you have an appropriate View-Window to
see the graphs drawn.
By separating each graph by a colon ‘:’ the calculator
generates them as a ‘collective’. Tracing each to nd
vertices etc is activated in the usual way, i.e. [SHIFT] [F1]
and then
arrows to trace the graph and the to
move from one graph to another.
