Homework Statement

I'm Having a hard time grasping what seems to be a simple topic-the parametrization and vector representation of curves...As a result it's making finding unit Tangent vectors and the length of Curves a nightmare :(

Please does anyone have any good resources they would recommend I use?
Or could someone dumb down this topic for me?

Any help will be really appreciated..

Homework Equations
