While graphs for cosine and sine functions are similar, those for tangent functions differ significantly from them, sharing only in that they show periodicity and symmetry. Recall \(\tan(x)= ...

This is a basic simulation of how a trigonometric graph (sin, cos, or tan) is created from a unit circle. Coded in Python 3.6 with the Pygame library. Use the big sin, cos, tan buttons to change the ...

Interactive content can be accessed via This Github Page. AutoPlaid plays with the properties of Lissajous curves Pressing the arrow keys changes the angleMod modifiers within the sin and cos ...

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 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 ...

Trigonometry is the branch of mathematics that explains the relationship between sides and angles of a triangle. In a right angled triangle the three sides are perpendicular, base and hypotenuse, as ...

Let’s look at how to use trigonometric identities to calculate missing sides. \({sin~θ} = \frac {opposite} {hypotenuse}\) \({cos~θ} = \frac {adjacent} {hypotenuse ...

from math import sin, cos, pi print(sin(pi/2)) # 1.0 print(cos(pi/2)) # 6.123233995736766e-17 The actual methods by which sin and cos are calculated are rather complicated (I’ll return to this in ...
