# Graphs of the Secant and Cosecant Functions.

Representation through more general functions. The secant function can be represented using more general mathematical functions. As the ratio of one and the cosine function that is a particular case of the generalized hypergeometric, Bessel, Struve, and Mathieu functions, the secant function can also be represented as ratios of one and those special functions. In numerical analysis, the secant method is a root-finding algorithm that uses a succession of roots of secant lines to better approximate a root of a function f.The secant method can be thought of as a finite-difference approximation of Newton's method.However, the method was developed independently of Newton's method and predates it by over 3000 years.

Trigonometric functions are used to model many phenomena, including sound waves, vibrations of strings, alternating electrical current, and the motion of pendulums. In fact, almost any repetitive, or cyclical, motion can be modeled by some combination of trigonometric functions. In this section, we define the six basic trigonometric functions and look at some of the main identities involving. The secant curves will open upward along the vertical asymptotes over intervals where the secant function lies above the mid-line. The secant curve will open downward along the vertical asymptotes over intervals where the cosine function lies below the mid-line. Both the secant function ad the cosine function are graphed in Figure 16.6.20.

## Easy Problems - Secant and Cosecant Functions. In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) are real functions which relate an angle of a right-angled triangle to ratios of two side lengths. They are widely used in all sciences that are related to geometry, such as navigation, solid mechanics, celestial mechanics, geodesy, and many others. Demonstrates how to graph the secant and cosecant curves, especially as they relate to the cosine and sine waves. Includes how to find the asymptotes. Graph of a General Secant Function General Form The general form of a secant function is: L m: n F o; E p. In this equation, we find several parameters of the function which will help us graph it. In particular: Amplitude: m L. Secant Function for Numeric and Symbolic Arguments. Depending on its arguments, sec returns floating-point or exact symbolic results. Compute the secant function for these numbers. Because these numbers are not symbolic objects, sec returns floating-point results. Secant Line Solver Added Aug 1, 2010 by regdoug in Mathematics This widget is built to solve for the slope of a secant line of a function with only one variable between the specified points. To find the x-intercepts and asymptotes of secant, cosecant, and cotangent, rewrite them in terms of sine and cosine. Notice that since secant and cosecant have 1 in the numerator and a trig function in the denominator, they can never equal zero; they do not have x-intercepts.

## Approximating Function Values Using Secant and Tangent Lines.

Secant method is the most effective approach to find the root of a function. It is based on Newton-Raphson method, and being free from derivative it can be used as an alternative to Newton’s method.The C program for Secant method requires two initial guesses, and the method overall is open bracket type. Also, the secant method is an improvement over the Regula-Falsi method as approximation.SECANT METHOD. The Newton-Raphson algorithm requires the evaluation of two functions (the function and its derivative) per each iteration. If they are complicated expressions it will take considerable amount of effort to do hand calculations or large amount of CPU time for machine calculations.Start studying Loci, Equation of A Circle, Systems, Equation of Tangent and Secant.

By using this website, you agree to our Cookie Policy.The Secant Method has wider applicability than just finding approximations to square-roots. Consider a continuous and continuously differentiable function f. All that this means for our purpose is that the graph of such a function can be approximated by a straight line segment over very short intervals. The Secant Method assumes more than this.
