Sine and cosine are cofunctions, which means that their angles are complementary. Consequently, sin (90° - x) = cos x. Secant is the reciprocal of cosine so that sec x = 1/(cos x). Knowing these properties of trigonometric functions, among others, will really help you in other advance math courses.

sine = sqrt(1 - cosine^2)sine = secant/sqrt(secant^2 - 1)

cosine = sqrt(1 - sin^2)

cosine = 1/secant

secant = 1/sqrt(1 - sine^2)

secant = 1/cos
