Parameter Names

Top  Previous  Next

Parameter names start with a $ sign, followed by a letter or letters and numbers. Note the following.

 

1.        Single letter parameter names are easier to manage than multiple letter names. Using longer parameter names creates unwieldy equations.

2.        Parameter names which include numbers tend to be confusing and are best avoided.

 

$p, $h, $x, $height, $length

 

are examples of valid parameter names.
