Why does cosine graph always start at 1?
It does not necessarily do so. f(x) = cos(x + 2) will not start at 1.
How do you graph cost revenue and profit functions?
There are a couple of graphs you could use. A pie graph or a bar graph.
What is the zero of a function and how does it relate to the functions graph?
A zero of a function is a point at which the value of the function is zero. If you graph the function, it is a point at which the graph touches the x-axis.
Can cosine x equal -3?
No.-1
Reciprocal of a cosine?
Reciprocal of Cosine is Secant
What is period as it pertains to the graph of sine and cosine?
Period is how long it takes for the sine and cosine functions to restart repeating themselves. Both have a period of 2pi (360 degrees).
What is the similarities between a sine graph and a cosine graph?
Both sine and cosine graphs are periodic functions with a periodicity of (2\pi), meaning they repeat their values every (2\pi) radians. They both have an amplitude of 1, oscillating between -1 and 1. Additionally, the sine graph is a horizontal shift of the cosine graph; specifically, the cosine graph can be expressed as the sine graph shifted to the left by (\frac{\pi}{2}) radians. Both graphs exhibit similar shapes, featuring smooth, continuous waves.
How can you tell if a graph is a sine function or a cosine function?
sine graph will be formed at origine of graph and cosine graph is find on y-axise
Which of the functions below could have created this graph?
To accurately identify which function could have created the graph, I would need to see the specific graph in question. However, common functions that often produce recognizable graphs include linear functions (straight lines), quadratic functions (parabolas), exponential functions (curved growth), and trigonometric functions (sine, cosine waves). If you provide details about the graph's shape or key features, I can help narrow down the possible functions.
Which trigonometric functions are even?
Cosine and secant are even trig functions.
Why are sine and cosine functions used to describe periodic?
because sine & cosine functions are periodic.
How do you find the max and min of sine cosine functions?
The maximum of the sine and cosine functions is +1, and the minimum is -1.
How do you use cosine?
cosine = adjacent/hypotenuse. It can be used as other trig functions can.
What are the keypoints for the graph of cosine?
For a general cosine graph, they would be the maximum and minimum values, and the values of the independent variable at which these are attained.Note that the graph of y = cos(x)+2 is never equal to zero, so there may not be any roots.
Does cosine create a line on a graph?
yes cos(x) makes a wave that starts on 0,1 you will have to graph it
Why it is named sinusoidal wave or sine wave in ac?
It's called a sine wave because the waveform can be reproduced as a graph of the sine or cosine functions sin(x) or cos (x).
How do you gradually increase the period of a cosine graph?
Increase the amplitude and the frequency
The length of one complete repetition of the cycle is called the what of the graph?
The length of one complete repetition of the cycle in a graph is called the period. In the context of periodic functions, the period is the distance along the x-axis after which the function's values repeat. For example, in trigonometric functions like sine and cosine, the period is typically (2\pi).
What is the difference between negative sine and cosine graphs and positive sine and cosine graphs?
The negative sine graph and the positive sine graph have opposite signs: when one is negative, the other is positive - by exactly the same amount. The sine function is said to be an odd function. The two graphs for cosine are the same. The cosine function is said to be even.
How does the graph of the cosine function differ from a graph of a sine function?
the graph of cos(x)=1 when x=0the graph of sin(x)=0 when x=0.But that only tells part of the story. The two graphs are out of sync by pi/2 radians (or 90°; also referred to as 1/4 wavelength or 1/4 cycle). One cycle is 2*pi radians (the distance for the graph to get back where it started and repeat itself.The cosine graph is 'ahead' (leads) of the sine graph by 1/4 cycle. Or you can say that the sine graph lags the cosine graph by 1/4 cycle.
What does cosine mean on a calculator?
The same thing that cosine means in trigonometry, a calculator just allows you to calculate such functions quickly.
What are functions in trigonometry?
The basic functions of trigonometry are: sine cosine tangent secant cosecant cotangent
What is the difference between a sine graph and a cosine graph?
The sine graph and the cosine graph are identical in shape, with the cosine graph shifted to the left by pi / 2, i.e. the sine starts at (x=0,y=0) and proceeds up with an initial slope of one, and the cosine starts at (x=0,y=1), and proceeds down with an initial slope of zero.
What is a cosine function?
A cosine function is a mathematical function defined as the ratio of the adjacent side to the hypotenuse in a right triangle, typically denoted as ( \cos(x) ), where ( x ) is the angle in radians. It is a periodic function with a period of ( 2\pi ) that oscillates between -1 and 1. The graph of the cosine function is a wave-like curve that starts at 1 when ( x = 0 ) and decreases to -1, then returns to 1. Cosine functions are widely used in trigonometry, physics, engineering, and signal processing.
