Lesson 7: Change of Domain

Change of Domain

Sometimes, you'll be asked to find solutions in different domains.
Previously you only needed to find solutions in , but in reality, the domain could be any amount of revolutions or part of you'd want.

Symmetric Domains

Solve

1. Split the domain
   
2. Consider each domain
   has no solutions, but does.
3. Find
   
4. Solve for x.

Asymmetric Domains

Solve

1. Find .
   .
2. Verify if

.

Quadratic Trig Domains

Solve for these domains:

1. Factor to make this easier
