Roots of sine and cosine functions
The aim of this work is to obtain a general formula for the roots of functions of the type f(x) = k sin(a(x − c)) + b, g(x) = k cos(a(x − c)) + b, for differents values of a, b, c and k. We start finding, for each one of the given functions, a root xR and the abscise xM of a maximum point which is a...

I10-R366-article-410562023-08-08T16:32:01Z Roots of sine and cosine functions Raíces de las funciones seno y coseno Degiorgio, Eduardo Farías, Guillermo Raíces de una función Seno Coseno Roots of a function Sine Cosine The aim of this work is to obtain a general formula for the roots of functions of the type f(x) = k sin(a(x − c)) + b, g(x) = k cos(a(x − c)) + b, for differents values of a, b, c and k. We start finding, for each one of the given functions, a root xR and the abscise xM of a maximum point which is adjacent of xR. From the distance between these two values and the period of the function, all the other roots are determined. El objetivo de este trabajo es obtener una formula general para hallar las raíces de funciones como f(x) = k sen(a(x − c)) + b, g(x) = k cos(a(x − c)) + b, para diferentes valores de a, b, c y k. Para ello se comienza hallando, para cada una de las funciones, una raíz xR y la abscisa xM de un punto maximo adyacente a ´ xR. A partir de la distancia entre estos dos valores y del per´ıodo de la funcion se determinan todas las demás raíces.

The aim of this work is to obtain a general formula for the roots of functions of the type
f(x) = k sin(a(x − c)) + b, g(x) = k cos(a(x − c)) + b,
for differents values of a, b, c and k. We start finding, for each one of the given functions, a root xR and the abscise xM of a maximum point which is adjacent of xR. From the distance between these two values and the period of the function, all the other roots are determined. |
