The cosine function is simply denoted as cos x, where x is the angle. In this article, we will learn the basic properties of the cosine, its graph, domain and range, derivative, integral, and its power series expansion of cosine. Cos x is a periodic function and has a period of 2π...
Euler's formulacosx= (eix+e-ix) / 2 Inverse cosine function Thearccosineof x is defined as the inverse cosine function of x when -1≤x≤1. When the cosine of y is equal to x: cosy=x Then the arccosine of x is equal to the inverse cosine function of x, which is equal to y...

The sine function is a function with values ranging from -1 to 1. The graph of sine is a continuous curve that repeats every {eq}2\pi {/eq} units or {eq}360^\circ {/eq}. Figure 3: Graph of y=sin(x) When given a triangle, {eq}sin(angle)=\frac{opposite}{hypotenuse} {/eq}...
What is the period of a graph? A periodic graph will eventually repeat its shape after intervals of a certain length. The length of each repeating cycle is called the period. How do you find the period of a cosine function? The period can be calculated using the formula T=2pi/B, where...
The graphical representation of the cosine function y = cos(x) is: The periodicity and the amplitude of the cosine function involve: The amplitude of the graph y = a cos(bx) is the number by which it varies above and below the x-axis. The amplitude is | a | The periodicity of the...
