or can you...
on most, if not all TI calculators, there is a button labeled "TEST".
the menu contains comparators such as <
and >
, but it also has a LOGIC tab.
this gives you access to conditional operators, like and
and or
.
since these will either return 1
(true
) or 0
(false
), they can cut off lines at certain points.
X>-5 and X<5
(-5, 1)
to (5, 1)
.0
(false
), nothing will happen.(X>-5 and X<5)5
(X>-5 and X<0)(X+5)
(X>-5 and X<0)(X+5)+(X>-5 and X<0)
(X>-5 and X<0)(X+5)+(X>-5 and X<0)2
Y_{1}=(X>1 and X<1.25)
Y_{2}=(X>1 and X<1.25)1.25
Y_{3}=(X>1 and X<1.25)1.5
Y_{4}=(X>1 and X<1.25)1.75
Y_{5}=(X>1 and X<1.25)2
Y_{6}=(X>1 and X<1.25)2.25
Y_{7}=(X>1 and X<1.25)2.5
Y_{8}=(X>1 and X<1.25)2.75
Y_{9}=(X>1 and X<1.25)3
(0.25
is the default margin of each marker)
putting a horizontal line and 2 diagonal lines together will make a triangle. simple as that.
Y_{1}=(X>-5 and X<5)
Y_{2}=(X>-5 and X<0)(X+5)+(X>-5 and X<0)
Y_{3}=(X>0 and X<5)(-X+5)+(X>0 and X<5)
