There’s nothing like a zero?

The function y(t)=(1-t)^6 has only one unique zero value at t=1. Plot the graph for 0<=t<=2 with a sampling interval 0.001 and try zero finding to 10 significant figures (s.f.).

You will see that Newton-Raphson fails to converge to the requested accuracy.

What has gone wrong?
