In support of efforts to foreground functions as central objects of study in algebra, this study provides evidence of how secondary students use trigonometric functions in contextual tasks. The author ...

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 ...

In the paper, the authors present several inequalities for bounding the sums of two sine cardinal functions and the sums of two hyperbolic sine cardinal functions. These inequalities improve ...

In high school, you probably learned that trigonometric functions – like sine, cosine and tangent –can be derived, geometrically, from a circle (hence why trig functions are also known as “circular” ...

July 2, 2014. For speed control or positioning, drive controllers today demand high-resolution magnetic or optical position sensors, which require special integrated circuits for sensor signal ...

CSS, which stands for Cascading Style Sheets, or the language that styles and arranges how page elements appear on a website, will get support for trigonometry functions such as sine, cosine, tangent, ...
