Functions and commands 323

Substitute Returns the solution when a value is substituted for a variable

in an expression.

subst(Expr,Var(v)=value(a))

Example:

subst(1/(4+x^2),x=2) gives 1/8

Partial Fraction Returns the partial fraction expansion of a rational fraction.

partfrac(RatFrac)

Example:

partfrac(x/(4-x^2)) gives (1/(x-2)*-2))+(1/

((x+2)*-2))

Extract

Numerator Returns the numerator of a fraction (after simplifying the

fraction if necessary).

numer(Frac(a/b) or RatFrac)

Example:

numer(10,12) returns 5

Denominator Returns the denominator of a fraction (after simplifying the

fraction if necessary).

denom(Frac(a/b) or RatFrac)

Example:

denom(10,12) returns 6

Left Side Returns the left side of an equation or the left bound of an

interval.

lhs(Equal(a=b) or Interval(a...b))

Right Side Returns the right side of an equation or the left bound of an

interval.

rhs(Equal(a=b) or Interval(a...b))

Calculus

Differentiate With one expression as argument, returns derivative of the

expression with respect to x. With one expression and one

variable as arguments, returns the derivative or partial

derivative of the expression with respect to the variable. With
