It is a fruitful formula, and many properties of complex functions can be derived from it. It also extends into the "fundamental theorem of algebra", a variety of basic theorems on the holomorphy of complex functions, and the power series expansion of complex functions....
Depending on the context, derivatives may be interpreted as slopes of tangent lines, velocities of moving particles, or other quantities, and therein lies the great power of the differential calculus. An important application of differential calculus is graphing a curve given its equation y = f(x...
To fix the notation, let us callXas the dataset for training. This contains several instances ofn-dimensional curves with respect to time. In other words, we consider\(X={\{{X}_{i}\}}_{i\le N}\), whereNis the number of instances and\({X}_{i}=\{{{\bf{x}}}_{0}^{i},\l...
2.In the article,some evaluations for the first kind ofimproper integrals ∫~∞_0sin(βx)x~ncos(bx)dx for positive integer n 1 and real numbers β≠0,b 0 are established using the trigonometric power formulae, the L′Hospital rule,integration by part,and mathematical induction.利用分部积分...
of a Fourier series of the functionf(x). Formula (2) is one of the most important formulas in the theory of Fourier series; in particular, it enabled Dirichlet to show that the Fourier series of a function with a finite number of maxima and minima converges at every point. ...
point case (and forin the limit circle case) is constructed and it is shown that the corresponding Weyl function coincides with the principal Titchmarsh–Weyl coefficient of the integral system. The notion of the dual integral system is introduced by reversing the order ofRandWand the formula rel...

definite integral is defined informally as the signed area of the region in the xy-plane that is bounded by the graph of f, the x-axis and the vertical lines x = a and x = b. The area above the x-axis adds to the total and that below the x-axis subtracts from the total.
First, the Green's function G is singular when x→ y so we need to consider the behavior of the integrals involving G and n·∇G for y on the boundary and as x→ y. Second, we derived this formula using the definition of the δ function, where we assumed that the point y was ...
For the calculation of the S using the formula S = −Vth/ΔT, it is necessary to ensure that the assumption of a uniform S across the entire film and a negligible ΔT along the Hall bar is met. Hence, the selection of the current passing through the micro-heater was made in a ...
