👉 In the context of mathematics, "gyered" is a mathematical operation that involves rotating a vector or matrix by an angle. It is commonly used in linear algebra and geometry to represent rotations. The operation can be defined as follows: 1. Define the rotation matrix R. 2. Rotate the vector u from the original position (0, 0) to its new position (cos(θ), sin(θ)). 3. Return the rotated vector. Here's a simple Python function that implements this
