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.
Why does cosine graph always start at 1?
It does not necessarily do so. f(x) = cos(x + 2) will not start at 1.
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.
Reciprocal of a cosine?
Reciprocal of Cosine is Secant
What is the cosine of -90?
Cosine of -90 is 0.
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).
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 trigonometric functions are even?
Cosine and secant are even trig functions.
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.
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.
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).
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
How do you gradually increase the period of a cosine graph?
Increase the amplitude and the frequency
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.
