Laplace Transformation

[latexpage] $1. History⟶$ Integral transformation data back to the Work of Leonard Euler (1763 & 1769), who considered them essentially in the form of the inverse Laplace transform in solving second-order, linear ordinary differential equations. Even Laplace, in his great work, “Theorie...

Fourier Series

1. INTRODUCTION The study of a special type of series whose terms are trigonometric functions of a variable was started in the 18th century when J.B.J. Fourier (1768-1830) was successful in his attempt to prove that an arbitrary function given in the interval $[-\pi,\pi]$ can be expressed under...

Riemann Integral

The story of integration started with I. Newton, when in the late 1660 he invented the method of inverse tangents to find areas under curves. In 1680, G. Leibnitz discovered the process of finding tangent line to find area. Thus, they had discovered the integration, being a process of summation,...

Lebesgue Outer Measure

The Riemann integral of a bounded function over a closed, bounded interval is defined using approximations of the function that are associated with partitions of its domain into finite collections of subintervals. The generalization of the Riemann integral to the Lebesgue integral will be achieved...

Continuity – Calculus

Welcome again to another article!!! This time with a new article in Calculus, and the topic of our journey this time is Continuity; so, after introducing the concept of limits of a function, their properties, and the different operations on limits alongside presenting the indeterminate forms that...

How to Improve Your ACT Math Score

The ACT Math section, like the other sections of the test, does not test what you know so much as it tests how well you can apply what you know. The actual math on the test is not easy, but it's not as difficult as you probably imagine. For most questions, the primary challenge is figuring out...
