Challenge Problems
Push your limits with challenges.
Question 1
If a vector (2, 0, 0) is rotated 90 degrees around the z-axis, what will be its new coordinates?
💡 Hint: Use the rotation matrix: R = [[0, -1, 0], [1, 0, 0], [0, 0, 1]].
Question 2
Consider a 3D object being rotated in a simulation. How can rotation tensors ensure that its size remains consistent?
💡 Hint: Reflect on the properties of orthonormal matrices.
