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.


How do you solve this graphing equation y plus x equals 6?

The solution consists of the infinite number of points on the line which is defined by y + x = 6.


What is the range of a a function f when it is defined by f x 2 cos 3 x where x is a real number?

f(x) = 2 cos 3x The amplitude: A = |2| = 2 The maximum value of the function: 2 The minimum value of the function: -2 The range: [-2, 2]


When is the Square root of x greater than x?

when x is a negative number --- is a wrong answer since square root of a negative number is not defined. So x has to be zero or a positive number. The correct answer is that when x lies between 0 and 1 (with both limits excluded), its square root is greater than the number itself. Of course at both limits, the square root (assuming the positive square root - since a square root of a number can be positive or negative, both with the same absolute value) is the same as the number.

Why cant the adsolute value of a number be negtive?

That is because of the way the absolute value is defined. The absolute value of a positive number is positive, the absolute value of a negative number is also positive. The absolute value of zero is zero. Even in the complex numbers, the absolute value is defined in such a way that it is a real and positive number.


Why does a negative number plus a negative number equal a positive number?

It does not. A negative number multiplied by a negative number equals a positive number.


Does a negative number minus a positive number equal a positive or a negative?

A negative number minus a positive number equals a minus number( E.G -5 - [+]5 = -10)A negative number minus a negative number equals a positive number ( If the number's big enough)(E.G -5 - -5 = 0 )Hope this helps :)
