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
Convert the polar
r
coordinates = 2 ,
= /4 to rectangular
coordinates.
Derivative Symbol (')
A single derivative symbol indicates the first derivative of an equation in the format:
<variable name>'.
Problem
Solve the differential
y x
equation ' = .
y x
{ = 0.5 · 2 + const (1)}
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.
Primality Te t (i Prime)
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
Determine whether the
numbers 51 and 17 are
prime.
(isPrime({51, 17})
