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 Te s t (i s 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

numbers 51 and 17 are
prime.
