No, you need to type some more. :-)  You need to define function
    def f(x):
	return x + 1
and call root solver, either from a library or function imported from
module.

For simple cases, I use RPN calculator recently added to Bash shell,
like
    rpn 'f(x)= 1 +' 0 1 secant =
    rpn 'f(x)= 1 +' 'fd(x)= 1'  0 newton =
