Why in fourier series constant is divided by two?
In Fourier series, the constant term, or the average value of the function over one period, is divided by two when computing the Fourier coefficients. This is because the constant term corresponds to the zero-frequency component, which represents the average value of the periodic function. When calculating the Fourier series, the coefficients are derived from integrals that include the full period of the function, leading to the factor of ( \frac{1}{2} ) for the constant term to ensure accurate representation. This adjustment maintains the overall balance of the series in reconstructing the original function.
What is the tanget of 90?
The tangent of 90 degrees is undefined. This is because the tangent function is defined as the ratio of the sine to the cosine, and at 90 degrees, the cosine is zero, leading to division by zero. Therefore, the tangent approaches infinity as the angle approaches 90 degrees.
Can the leading coefficient of a polynomial function be a fraction?
Yes, the leading coefficient of a polynomial function can be a fraction. A polynomial is defined as a sum of terms, each consisting of a coefficient (which can be any real number, including fractions) multiplied by a variable raised to a non-negative integer power. Thus, the leading coefficient, which is the coefficient of the term with the highest degree, can indeed be a fraction.
What is a polynomial function f of least degree that has rational coefficient a leading coefficient of 1 and the given zeros -7 -4?
A polynomial function of least degree with rational coefficients and a leading coefficient of 1 that has the zeros -7 and -4 can be constructed using the fact that if ( r ) is a zero, then ( (x - r) ) is a factor. Therefore, the polynomial can be expressed as ( f(x) = (x + 7)(x + 4) ). Expanding this, we get ( f(x) = x^2 + 11x + 28 ). Thus, the polynomial function is ( f(x) = x^2 + 11x + 28 ).
Why does the square root function have a restricted domain?
The square root function has a restricted domain because it is defined only for non-negative real numbers. This restriction arises from the fact that the square root of a negative number is not a real number, leading to complex results instead. To ensure that the function produces real outputs, the domain is limited to zero and positive values. Hence, for the function ( f(x) = \sqrt{x} ), the domain is ( x \geq 0 ).
When an odd function has a negative leading coefficient what happens to the graph?
the left end of the graph is going in a positive direction and the right end is going in a negative direction.
What is the rational zero theorem?
If a polynomial function, written in descending order, has integer coefficients, then any rational zero must be of the form ± p/q, where p is a factor of the constant term and q is a factor of the leading coefficient.
Which polynomial has rational coefficients a leading leading coefficient of 1 and the zeros at 2-3i and 4?
There cannot be such a polynomial. If a polynomial has rational coefficients, then any complex roots must come in conjugate pairs. In this case the conjugate for 2-3i is not a root. Consequently, either (a) the function is not a polynomial, or (b) it does not have rational coefficients, or (c) 2 - 3i is not a root (nor any other complex number), or (d) there are other roots that have not been mentioned. In the last case, the polynomial could have any number of additional (unlisted) roots and is therefore indeterminate.

What is the end behavior of a function?
The end behavior of a function is how the function acts as it approaches infinity and negative infinity. All even functions such as x^2 approach infinity in the y-axis as x approaches infinity and odd functions such as x^3 approach positive infinity in the y- axis as x approaches positive infinity and negative infinity in the y- axis as x approaches negative infinity. If their is a negative leading coefficient then it is just flipped.
What does it mean when the temperature of an enzymes at 35 degrees?
An enzyme operating at 35 degrees Celsius means it is working at an elevated temperature compared to typical human body temperature (37 degrees Celsius). This increased temperature may affect the enzyme's activity and stability, potentially leading to changes in its function.
At what temperature do most hypothermic deaths occur?
Most hypothermic deaths occur when the body's core temperature drops below 95 degrees Fahrenheit (35 degrees Celsius). This is when the body's ability to regulate its temperature is overwhelmed, leading to decreased organ function and, ultimately, death.
What condition you get negative regulation for transformer?
When its load has a leading power factor.
What are the elements of management and there function?
Planning, organizing, leading and controlling.
Is it possible for flux to have a negative value?
Yes, it is possible for flux to have a negative value. This occurs when the magnetic field and the area vector are in opposite directions, leading to a negative flux value.
Can alcohol affect IQ?
Yes, alcohol consumption can have a negative impact on cognitive function, which includes IQ. Excessive or prolonged alcohol use can impair memory, attention, and overall brain function, potentially leading to a decrease in IQ scores over time. It is important to consume alcohol in moderation to protect cognitive abilities.
What does a function on a graph look like?
A function is just a fancy name for a math problem. It could be a straight line or it could be a parabola or even some thing else. The key to knowing what it looks like is the leading coefficient. What is the highest power of x? Is it positive or negative? An x with the power of one will be a straight line at an angle.
