Assignment:
Show that: lim (x+y)=o as x and y approach zero; using the epsilon-delta definition.
Also, show that: lim f(x)=1 as x approaches zero; using the epsilon-delta definition.
Note: x is a vector in this case, with a right arrow going over it. It is not just "x".
Provide complete and step by step solution for the question and show calculations and use formulas.
