Expressions can contain numeric constants (in non-exponential notation),
variable names, the arithmetic operations +, -, *, /, and unary -.
variable names, the arithmetic operations +, -, *, /, unary -, and the
functions sin(), cos(), and sqrt().
Parentheses can be used to change precedence.
The argument of sin and cos is a dimensionless number that specifies the
angle in degrees. E.g., sin(90) yields 1.
The argument of sqrt() can be dimensionless or have a dimension with an
exponent that's a multiple of two. E.g., sqrt(2) and sqrt(2mm*3mm) are
valid expressions, sqrt(2mm) isn't.
