In this study, we investigate a new neural network method to solve Volterra and Fredholm integral equations based on the sine-cosine basis function and extreme learning machine (ELM) algorithm.

To solve trigonometric equations involving radian measure, you should proceed in the same way as for degrees. Use the diagram below to help you apply the necessary conditions. You should also know ...

Prerequisites: Credit for MATH 1314 with a grade of C- or higher, or a satisfactory score on a placement examination. Course Description: This course concentrates on the various subjects that are ...

To solve problems involving non-right-angled triangles, the correct rule must first be chosen. The cosine rule can be used in any triangle to calculate: a side when two sides and the angle in between ...

Abstract: Helmholtz equation is a special kind of elliptic partial differential equation. Solving Helmholtz equation is often needed in many scientific and engineering problems. The efficient approach ...

In this paper, the moment of various types of sine and cosine functions are derived for any random variable. For an arbitrary even probability density function, the sine and cosine moments are used to ...
