Secant Formula Math

In a formula it is abbreviated to just sec.

Secant formula math. As sec x 1 cos x 1 3 8 8 3. S e c x h y p o t e n u s e a d j a c e n t s i d e. So sec x 8 3. Consider the line connecting the endpoint values a f a and b f b.

Finding the equation of a secant line is a three step process. Find sec x if cos x 3 8. Secant line formula let f x be a continuous function on a closed interval a b such that f a f b 0. Sec x frac 5 4 secx 45.

Secant sec trigonometry function see also secant of a circle. Y y 1 m x x 1 finding the equation of a secant line. As we know that the formula for secant of angle x is. Secant is reciprocal of cos sec x frac 1 cosx examples of secant math formula.

Find the slope of the line that runs between the two points. In fact most calculators have no button for them and software function libraries do not include them. Thus substituting the values we get s e c x 5 4. Locate two points on the secant line.

In a right triangle the secant of an angle is the length of the hypotenuse divided by the length of the adjacent side. As we know there are six trigonometric functions and out of these secant cotangent and cosecant are hardly used. More about secant angles formula. The equation of the line through the two points can be found by using the slope point formula.
