The document discusses expressing trigonometric functions in terms of sine and cosine. It explains that secant can be expressed as the reciprocal of cosine, cosecant as the reciprocal of sine, tangent as sine over cosine, and cotangent as cosine over sine. The homework is to read the assigned pages and complete problems 1 through 12 on page 678.
