I've been working with sympy to use it on robot direct kinematics, however, it doesn't evaluate cos or sin functions, code attached below. import numpy as np from sympy import cos, sin, pi import ...

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 ...

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

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 ...
