"dx" here is still an infinitesimal change in x. To see why it's there, we should think of the integral as a signed area and as the limit of Riemann sums. We recall that to compute a left Riemann sum of f(x) from x=a to x=b with n intervals, we let the following be true...
What is the trapezium rule?What are trapeziums?Trapeziums are a form of quadrilateral sharing the same properties as the others in terms or number of sides (4), and sum of the measure of its angles (360{eq}^{\circ} {/eq}). In calculus, trapeziums are very useful as they are the...

We will record the proof of Theorem 1 below the fold; it largely follows the classical derivation of the BCH formula, but due to the low regularity one will rely on tools such as telescoping series and Riemann sums rather than on the fundamental theorem of calculus. As an application of th...
Infinities often arise when using “limits”, mathematical constructions which provide a rigorous backbone for calculus. When we have a function and write what we mean is the value (if one exists) that the function approaches as gets larger and larger. So, for exa...
Foundations of the calculusIntegrationRiemann sumA number of scholars have recently maintained that a theorem in an unpublished treatise by Leibniz written in 1675 establishes a rigorous foundation for the infinitesimal calculus. I argue that this is a misinterpretation. (C) 2017 Elsevier Inc. All ...
(But performing such an iteration would probably have been beyond the computational resources available in Kepler’s time; also, the foundations of perturbation theory require calculus, which only was developed several decades after Kepler.) 24:21 Did Brahe have exactly 10 years of data on Mars’...
What is nonlinear functional analysis? What is an implicit Euler method? Describe the fundamental theorem of calculus. Give one example or application. a) What is the Riemann hypothesis? b) Discuss the ideas underlying some of the notable attempts that have been unde...
The integral of x^2 is \frac{x^3}{3} plus a constant. Integral The fluent of a given fluxion in Newtonian calculus. Integral Lacking nothing of completeness; complete; perfect; uninjured; whole; entire. A local motion keepeth bodies integral. Integral Essential to completeness; constituent, ...
Zero is a fundamental concept in mathematics and represents a number with no value. It serves as a placeholder in our numeral system and plays an integral role in arithmetic, calculus, and other branches of mathematics. Null, on the other hand, stems from computing and database contexts and ...
