Coordinate transformation under rotation

In summary, coordinate transformation under rotation is the process of converting coordinates from one coordinate system to another after a rotation has been applied. This is important in various fields such as mathematics, physics, and engineering to describe the same point in space with different coordinate systems. There are two methods of transformation: active and passive, both achieving the same result but differing in the way the transformation is applied. The process involves using mathematical equations and matrices, and can also be applied to 3D coordinates in fields like computer graphics and robotics.

If a system is rotated around Z axis then the new coordinates are X'= xcos() - Y sin(),

Y'= Xsin() + Ycos()

Z'= Z

How is this obtained ??

() --->theta , angle of rotation around Z axis .

Simply look at rotating the basis vectors through an angle theta about the z-axis.

1. What is coordinate transformation under rotation?

Coordinate transformation under rotation is the process of converting coordinates from one coordinate system to another after a rotation has been applied to the original coordinate system. This is commonly used in mathematics, physics, and engineering to describe the same point in space with different coordinate systems.

2. Why is coordinate transformation under rotation important?

Coordinate transformation under rotation is important because it allows us to describe the same point in space with different coordinate systems, which is necessary for many scientific and engineering applications. It also helps us to better understand the relationship between different coordinate systems and how they relate to each other.

3. What is the difference between active and passive coordinate transformation under rotation?

Active coordinate transformation under rotation involves physically rotating the coordinate system, while passive coordinate transformation under rotation involves keeping the coordinate system fixed and changing the coordinates of points within the system. Both methods achieve the same result, but they differ in the way the transformation is applied.

4. How do you perform coordinate transformation under rotation?

The process of performing coordinate transformation under rotation involves using a set of mathematical equations and matrices to convert the coordinates from one system to another. The specific equations and matrices used will depend on the angle of rotation and the orientation of the coordinate systems.

5. Can coordinate transformation under rotation be applied to 3D coordinates?

Yes, coordinate transformation under rotation can be applied to 3D coordinates. The equations and matrices used will be more complex compared to 2D transformation, but the same principles apply. This is commonly used in computer graphics, robotics, and other fields that deal with three-dimensional space.
