Trigonometric Functions and Complex Numbers covers the followings areas in the International Mathematical Olympiad (IMO) and other mathematical competitions. Trigonometric identity, graphs and ...

Abstract: In this paper, we consider approximation to trigonometric polynomial function by using a one-hidden-layer feedforward neural networks, and obtain the upper bounds of trigonometric function ...

The sine and cosine functions can be used to model fluctuations in temperature data throughout the year. An equation that can be used to model these data is of the ...

Trigonometric identities are powerful tools for simplifying complex equations in math and science. Three core groups—reciprocal, quotient, and Pythagorean—form the foundation. Effective strategies ...

NCERT Solutions for Class 12 Maths Chapter 2 Inverse Trigonometric Functions: Keeping in mind the the upcoming CBSE Board Exam 2025, we bring to you in-depth NCERT ...

PERHAPS the best way of treating this work, which does not contain a single word of explanation, will be to give a summary of the tables contained in it. First we have proportional parts of all ...

We consider a method of estimating an unknown regression curve by regression on a combination of low-order polynomial terms and trigonometric terms. Estimation based on trigonometric functions alone ...

Abstract: A chaotic neural network with self-feedback of trigonometric function is presented by introducing non-linear trigonometric function as self-feedback of chaotic neural network. The reversed ...

This is a simple trigonometric function calculator implemented in MATLAB. It can calculate sine (sin), cosine (cos), arcsine (arcsin), and arctangent (arctan) functions. Users can input either radians ...
