Q2: What if I want to rotate a point around a different origin?Ī2: To rotate a point around an origin other than (0, 0), you would need to first translate the point to the desired origin, apply the rotation, and then translate it back. For 3D rotations, you would need additional parameters, such as rotation axes and angles. Q1: Can I use this calculator for 3D rotations?Ī1: This calculator is specifically designed for 2D rotations in a Cartesian coordinate system. So, after rotating the point (3, 4) counterclockwise by 45 degrees, you get the new coordinates (-√2, 7√2/2). Suppose you have a point with coordinates (3, 4), and you want to rotate it counterclockwise by 45 degrees (π/4 radians) around the origin (0, 0). Let’s illustrate the concept with an example: Interpret the results: The new coordinates represent the point’s position after the specified rotation.Calculate the new coordinates: The calculator will apply the rotation formula and provide you with the new coordinates (x’, y’).Keep in mind that positive angles correspond to counterclockwise rotation. Specify the rotation angle: Enter the angle of rotation in radians.Input the original coordinates: Enter the initial x and y coordinates of the point you want to rotate.Using the Rotation Calculator is a straightforward process: (x’, y’) represents the new coordinates after rotation.
