## Homework Statement

r(t)- ln|t-1| i , e^t j , sqrt(t) k find the natural domains. this is a problem as an example in the book.

## Homework Equations

It gives an answer of (-infinity,1) U (1,+infinity), (-infinity,+ininity) and [0, +infinity) and the intersection of these sets are [0,1) U (1,+infinity) then it says that the naturals domain of r(t) is 0=< t <1 or t >1
