Sine, cosine and tangent functions are periodic functions, meaning they repeat themselves at regular intervals. This interval of repetition is known as the period of the function, and this periodicity ...

It is an project for experiment on all trigonomatric functions with core graphics. Just download the project and experiment withe sin, cos, tan, cot, sec, cosec functions. Look at the waves, adjust ...

I am have a slight problem with two recursive functions I wrote: Sine and Cosine. Each function depends on the other (and itself) to compute the value of Sine and Cosine for any value input. I am ...

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 ...

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 ...

This circle has the centre at the origin and a radius of 1 unit. The point P can move around the circumference of the circle. At point P the \(x\)-coordinate is \(\cos{\theta}\) and the ...

Abstract: A fast and stable algorithm for approximation of sine and cosine hyperbolic functions is presented in this paper. The algorithm can be used for S-parameter calculation from RLGC parameters.
