Trigonometric Sec Table

Secant is the inverse function of cosine. The secant, sec is the reciprocal of cos function. It is the ratio of the length of the hypotenuse to the length of the adjacent side. Military makes use of secant trigonometric function. The secant graphs are mainly used in the area of ballistic trajectories. Make use of table listed below to determine the degree values of sec function.
