SOL Tips and Tricks




PUT CALCULATOR ON a + bi (in MODE)
STAT DIAGNOSTICS ON (in MODE)
Zoom 6 for a normal -10 to 10 screen when graphing
APHA WINDOW for shortcut menu to lots of good stuff (much of which can
be found in the math menu)
 Helpful Apps – Inequalz (absolute value with x and y) and PlySmlt2 (solving
quadratics and finding factors)
“SIMPLIFY” – “EQUIVALENT EXPRESSIONS” – “FACTOR”
o 
sto
x
o Type in given expression, type in answers options
“SOLVE EQUATIONS” – “FIND SOLUTIONS” – “FIND ROOTS”
o Store each answer option as x, plug and chug!
o Not a multiple choice question –
Put left side in Y1
Put right side in Y2
2nd Trace #5 enter enter enter
The x-value is the solution.
o If equation is set equal to zero, look for the x-value where the graph
crosses the x-axis
2nd Trace #2
o Solutions = roots = zeros = x-intercept
FIND FACTORS
o Solution: x = a
Factor: (x – a)
o Find factors using PlySmlt2 App
o If solution has a fraction, slide the denominator in front of
the x
ABSOLUTE VALUE INEQUALITY – ONLY X
o Type into Y=, use 2nd Math menu for inequality symbol
o Look for part of graph ABOVE the x-axis
o Less Than
 (open) ≤ (closed)
o Greater Than  (open) ≥ (closed)
ABSOLUTE VALUE INEQUALITY – X AND Y
o Use Inequalz App to use appropriate inequality symbol
REGRESSION – CURVE OF BEST FIT – EQUATION THAT BEST MODELS
1. Put information in L1 and L2 STAT Edit
2. Plots on – highlight Plot 1 in y=
3. Zoom 9 to see scatter plot and determine function
4. Stat  Calc then choose function
5. Store RegEq – Y1 ( Alpha Trace #1) **DON’T SKIP THIS STEP!**
6. Not sure of function? Find r2 closest to 1
7. Given a time and looking for y? 2nd Window and type in number to
TblStart, then go into table 2nd Graph
