Notes on Some Remedies. XV. Drugs in Syphilis (Contd.)
Syphilis attacks the blood vessels after a long latent period, and then the brunt of the attack falls on the aorta at its origin. It is a chronic inflammatory process of the vessel wall leading to dilatation and regurgitation or anginal attacks by implicating the mouths of the coronary arteries. In the past too energetic treatment with powerful remedies was the cause of rapid heart failure from...
متن کاملNotes on Fourier Series
A function or a real variable f is said to be periodic with period P if f(x+ P ) = f(x) holds for all x. Hence, if we know the values of f on an interval of length P , we know its values everywhere. If f is a function defined on an interval [a, b), we can extend f to a function defined for all x which is periodic of period b− a. We simply define f(x) to be f(x+ n(b− a)), where n is the integer ...
متن کاملNotes on Chebyshev Series and Computer Algebra
A typical computer algebra system (CAS) represents formulas by (what amounts to) trees. By approximating a more general function as a univariate polynomial, it can be represented as an array of coefficients. Another common representation is as a set of values of the function at specified points. In either case, one can compute in this realm of “functions” further by combining such arrays. By ta...
متن کاملNotes on Infinite Sequences and Series
We represent a generic sequence as a 1 , a 2 , a 3 ,. .. , and its n-th as a n. In order to define a sequence we must give enough information to find its n-th term. Two ways of doing this are: 1. With a formula. E.g.: a n = 1 n a n = 1 10 n a n = √ 3n − 7 2. With a recursive definition. 1.2. Limit of a Sequence. We say that a sequence a n converges to a limit L if the difference |a n − L| can b...
متن کاملNotes on double inequalities of Mathieu's series
Using the integral expression of Mathieu's series and some integral and analytic inequalities involving periodic functions and the generating function of Bernoulli numbers, we present several new inequalities and estimates for Mathieu's series and generalize Math-ieu's series. Two open problems are proposed.
