Only square matrices can have a determinant. One of the original uses of a determinant of a matrix had to do with solving a system of linear equations. Once the determinant of a matrix had been calculated, that number could be used to help quickly compute the solution to a system of equations.
A physician assistant may perform medical services when under the supervision of a physician. Medical services which may be performed by a physician assistant include a referral to a physical therapist for treatment. In making such a referral, the physician assistant is acting as the agent of the physician.ew York State law restricts the practice of physical therapy to licensed physical therapists or certified physical therapist assistants. Individuals who are not licensed or certified may not provide physical therapy services.
Physical therapist assistants who are members of the APTA and have at least five years of work experience, 60 hours of continuing education credits, a letter of recommendation and demonstrated leadership abilities may qualify for this credential.
