using the theory vs rely on the theory

Both phrases are correct, but they are used in different contexts. 'Using the theory' implies actively applying a theory in practice, while 'rely on the theory' suggests depending on a theory for support or guidance. The choice between the two depends on whether you are talking about practical application or trust in the theory.
