How do you get a period of 3 in a cosine function?
The argument of the cosine function must be (2pi/3)*x radians
What does a period mean in maths?
A function f(x) of the variable x, has a period k where k is some constant, if f(x+ k) = f(x) for every x. It is easy to show that f(x + nk) = f(x) for any integer n. What the above two formulae imply is that the values of the function repeat after an interval (or period) of k. The trigonometric functions are some of the better known periodic functions.
What is the period of y equals tan2x?
The period of the tangent function is PI. The period of y= tan(2x) is PI over the coefficient of x = PI/2
Is log periodic function?
No. It is an increasing function, with a domain of x > 0. An example of a periodic function is y = sin x. It repeats with every period and keeps crossing, back and forth, over the x-axis. y = log x doesn't behave that way. It just keeps increasing, without limit, as x increases.
An even function of minus x does not equal the function of positive x for all values of x -a composite function which results from the function of g within the function of x?
The first part of the question is false, and the correct answer is that an even function of minus x equals the function positive x. This follows from the very definition of an even function. The second part of the question is false, because the truth is that the composite function results from taking the function of x within the function g.
What are periodic functions?
A nonconstant function is called periodic if there exists a number that you can add to (or subtract from) the argument and get the same result. The smallest such positive number is called the period. That is, nonconstant function f(x) is periodic, if and only if f(x) = f(x + h) for some real h. The smallest positive such h is the period. For example, the sine function has period 2*pi, and the function g(x) := [x] - x has period 1.
Which functions has a period?
You can invent any function, to make it periodic. Commonly used functions that are periodic include all the trigonometric functions such as sin and cos (period 2 x pi), tan (period pi). Also, when you work with complex numbers, the exponential function (period 2 x pi x i).
What is the period of a trig function?
The period of trigonometric function is the distance between repetitions of the function. The "x" value of the space it takes to start over.
What is the period for y-3 sin x?
y = 3 sin x The period of this function is 2 pi.
What is the period of tan x?
The period of the function y= tan(x) is pie The periods of the functions y= cos(x) and y= sin(x) is 2pie
What is the period of tan?
The period of the function y= tan(x) is pie The periods of the functions y= cos(x) and y= sin(x) is 2pie
Which function's graph has a period of 2?
There are an infinite number. The simplest is a sinusoid. The sine function has period 2π, so you compress it by a factor of π: f(x) = sin (πx).
Math formula for period?
A function f(x) has period t if t is the smallest value such thatf(x+t) = f(x) for all x in the appropriate domain.
Why is the period of secant 2 pi?
It is the same period as cosine function which is 2 pi because sec x = 1/cos x
What is the period of the function y equals 2sin x?
2 pi
How do you get a period of 3 in a cosine function?
The argument of the cosine function must be (2pi/3)*x radians
What is the period of the function f(x) cos 10x?
It is pi/5 radians.
