This sum is called a Chebyshev series or a Chebyshev expansion. Since a Chebyshev series is related to a Fourier cosine series through a change of variables, all of the theorems, identities, etc. that apply to Fourier series have a Chebyshev counterpart. [16] These attributes include: The Chebyshev polynomials form a complete orthogonal system.
Clenshaw–Curtis quadrature and Fejér quadrature are methods for numerical integration, or "quadrature", that are based on an expansion of the integrand in terms of Chebyshev polynomials. Equivalently, they employ a change of variables x = cos θ {\displaystyle x=\cos \theta } and use a discrete cosine transform (DCT) approximation for ...
One can obtain polynomials very close to the optimal one by expanding the given function in terms of Chebyshev polynomials and then cutting off the expansion at the desired degree. This is similar to the Fourier analysis of the function, using the Chebyshev polynomials instead of the usual trigonometric functions.
Aug. 16—Mayo Clinic is expanding its proton beam therapy program by spending $200 million to build a new 110,000-square-foot facility in downtown Rochester. The announcement was made this ...
The Mayo Clinic announced a $5 billion expansion plan for its flagship campus Tuesday that includes new buildings designed so they can evolve and expand as patient needs change over the coming ...
As a result of its generality it may not (and usually does not) provide as sharp a bound as alternative methods that can be used if the distribution of the random variable is known. To improve the sharpness of the bounds provided by Chebyshev's inequality a number of methods have been developed; for a review see eg. [12] [37]
The Chebyshev pseudospectral method for optimal control problems is based on Chebyshev polynomials of the first kind. It is part of the larger theory of pseudospectral optimal control , a term coined by Ross . [ 1 ]
The Gonda building was the largest building project in the Mayo Clinic's history, the Leslie & Susan Gonda Building was constructed in three phases to a height of 21 stories. A fourth phase is planned for completion in the 2020s. Located at the heart of the campus, Gonda is the centerpiece of Mayo's integrated practice.
