This post begins a series on how sin and cos are calculated in the c language standard math library on a typical Linux system. Because Python floats are really c doubles, what I write here applies to ...

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 ...

Sin and Cos often need to be calculated together, which is a very long operation, because they have to be calculated spearately. In some scientific calculations (e.g. my current project) this may ...

Revise using the sine and cosine rules to find a side or angle in a triangle for National 5 Maths. National 5 Maths - Using the sine and cosine rules to find a side or angle in a triangle.

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on ...

(I have no idea why POLYNOMIAL is defined in terms of POLYNOMIAL2 in this way. Neither is used anywhere else in the file.) and these numbers are close to, but not the nearest floats to, the ...

Trigonometry is often aligned with right-angled triangles only. However, an understanding of trigonometry can also be extended to non-right angle triangles to find unknown sides or angles. The Sine ...

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 ...

This Expression Shorts episode, explores Math.sin() in greater detail. In this part 1 episode I show you how to create pendulum style motion, swinging style motion with decay, and circular motion.
