# SecantMethodFindRoot

Determine the root of an equation using the secant method

Contributed by: Jason Martinez
 ResourceFunction["SecantMethodFindRoot"][f,{x,x0,x1},prec] searches for a numerical root of f starting at x0 with digits equal to prec. ResourceFunction["SecantMethodFindRoot"][lhs⩵rhs,{x,x0,x1},prec] searches for a numerical solution to the equation lhs==rhs. ResourceFunction["SecantMethodFindRoot"][f,{x,x0,x1},prec,property] returns a property of the search for the root of f.

## Details

ResourceFunction["SecantMethodFindRoot"] supports two options for property:
 "Solution" return the root of f "Steps" return a table of steps taken to reach the root
"PropertyAssociation" can be used to return an Association of the properties.
