I Angle Symbol ()
Use this symbol to specify the coordinate format required by an angle in a vector.
You can use this symbol for a vector only.
Problem
Use this keyboard:
Operation
mth abc cat 2D
Convert the polar
coordinates
r = 2 ,
Q = P
coordinates. [1, 1]
OPTN Func Change the [Angle] setting to
“Radian”.

I Derivative Symbol (’)
A single derivative symbol indicates the first derivative of an equation in the format:
<variable name>’.
Problem
Use this keyboard:
Operation
mth abc cat 2D
Solve the differential
equation
y ’ = x .
{ y = 0.5 · x 2 + const (1)}
CALC SMBL Cmd [dSolve] 8 7 7

Important!
The “dSolve” function can solve differential equations up to three degrees, so a maximum of
three derivative symbols (y’’’) can be used. Executing a “dSolve” calculation that has more
than three derivative symbols will result in an Invalid Syntax error.
I Primality Test (isPrime)
The “isPrime” function determines whether the number provided as the argument is prime
(returns TRUE) or not (returns FALSE). The syntax of the “isPrime” function is shown below.
isPrime(Exp/List[ ) ]
• Exp or all of the elements of List must be integers.
Problem
Use this keyboard:
Operation
mth abc cat 2D
Determine whether the
numbers 51 and 17 are
prime.
(isPrime({51, 17}) Func [isPrime] W 51 17
