Syntax
series(Expr,Equal(var=limit_point),[Order],[Dir(1,0,-1)])
Description
Returns the series expansion of an expression in the vicinity of a given equality variable. With the optional third and fourth arguments you can specify the order and direction of the series expansion. If no order is specified the series returned is
fifth order. If no direction is specified, the series is bidirectional.
Example
series((x^4+x+2)/(x^2+1),x=0,5) returns 2+x-2x^2-x^3+3x^4+x^5+x^6*order_size(x)
