Everything you need to know that your calculator does

Modes
•0: Normal –Used for calculations such as differentiation, summing
and integration.
•1: Stat –Easy to use statistics mode
•2: Drill –Practice your mental maths!
•3: Complex numbers –Calculate conjugates, change between polar
and rectangular coordinates, and so on.
•4: Matrix –Matrix calculations including derivative, transpose and
inverse of up to 4 x 4 matrices.
•5: List –Input data and use mode to sort data in ascending or
descending order, find the mean and standard deviation.
•6: Equation –Solve quadratic and cubic equations, as well as
simultaneous equations.
•Press and the number of the mode you want to go to.

0: Normal Mode
•Displays equations in
writeview (i.e. just like the
textbook).
•Solves equations
•Integrates and differentiates
•Does 44 different conversions
and has 52 constants

Shortcut for Class marks
•If you want to convert
between the total of your test
or exam to another total.
•E.g. If you have an test out of
40 and want to work out
percentages.
•You are converting from 40 to
100

between two points:
•Press
•Type in where the integral
starts, press your right or up
arrow key.
•Type in where the integral ends.
Press the right or up arrow
•Type in the expression you want
to integrate. Press twice to
get an x.

Integration example

Differentiation
•Press
•Type in the expression you want
to differentiate.
•Remember to press
twice to get an X.

Differentiation Example
•To find the derivative of
 at   
•Press

Function
•Press
•Type in where you want to start
the sum from.
•Press the right arrow key.
•Type in where the sum ends.
•Press the right arrow key.
•Type in the expression you are
summing over. Remember to
press twice to get an X.

Summing Example

Random Function
•Press 7
•4 options:
•0: RAND –Random decimals
between 0 and 1 to three decimal
places.
•1: R-DICE –Random numbers
between 1 and 6
•2: R-COIN –Instead of heads and
tails we have 0’s and 1’s.
•3: R-INT –Random numbers
between 0 and 99.
•Press to generate the
random numbers

Degrees / Radians
•Press MODE 0
•e.g. 180
•Press 180
•Press

Memory Functions
•You have several different
memory keys that can be used.
•Letter memory keys allow you
to save a value to each letter.
These are great for doing
substitution questions.
•ANS memory, saves the last
answer to be used in your next
calculation.
•The D-keys save a calculator
function for quick access.

Substitution
•Use to save a value to a
memory key, use to see
what value is saved in the
memory key.
•E.g.    
•A = 4, B = -2 and C = 5
•Store these values:
•4 CNST
•2
•5

Substitution
•Use to call the memory
key in an expression
•Now type in the expression:
•E.g.    
•CNST
•3
•
•

Last Answer
•As a simple example press 3
+ 4 =
•Now if we want to use the
answer (in this case 7) in our
next calculation we press
•E.g. 12 -
