Introduction to Rotation Calculator:
Rotation calculator geometry is an online tool that helps you to find the rotation geometry of a given function about its center axis. It is used to evaluate the rotating point of an object around a specific axis by a certain angle in a fraction of a second.
The rotations calculator is a helpful source for students, teachers, and researchers as it is widely used in various fields like computer graphics, robotics, engineering, and physics.
What is Rotation?
Rotation is the movement of an object around a specific point or axis in mathematics. In two dimensions the rotation is present around the origin (0,0) coordinates around an axis and it is a fixed rotation of an object.
On the other hand in three-dimensional space, the object revolves around coordinate axes(x,y,z) by arbitrary angle. It is measured in degrees or radians. One rotation of an object is around with 360° or 2πradians angle.
Formula of Rotation:
The formula for 180 degree rotation consists of a coordinate point in the x-y plane that has rotated by angle θ along the x-axis. The rotation formula used by the geometry rotation calculator is given below,
$$ X \;=\; x\; cos(\theta) + y\; sin(\theta) $$
$$ Y \;=\; -x\; sin(\theta) + y\; cos(\theta) $$
Whereas x is the coordinate of the x-axis y is the y coordinate value and θ is the angle of the rotational object.
How to Calculate the Rotation?
For calculating rotation, the rotation solver uses several steps including the rule for rotation, and the process varies depending on the form of the rotational object in 2D or 3D space. Here’s a step-by-step guide for rotation problem calculation.
For 2D Rotation:
For 2D rotation, the rotation graph calculator determines the rotation point so, you need to find the rotating point (x,y) around the origin by an angle θ.
Step 1:
Identify the rotation function problem and the angle value theta function.
Step 2:
Convert the given angle into radians if it is present in degree.
$$ X \;=\; x\; cos(\theta) + y\; sin(\theta) $$
$$ Y \;=\; -x\; sin(\theta) + y\; cos(\theta) $$
$$ Radian \;=\; \frac{degrees \times180}{π} $$
Step 3:
Calculate the rotation problem after applying the formula of the rotation object.
Step 4:
Put the value in the above formula and simply it.
Step 5:
After simplification, you will give the solution of the new coordinates (x′,y′) that are the result of the rotation.
Example of Rotation:
The rotation calculator helps you to determine the rotation point easily but its also essential to understand the step-by-step calculation process. So an example is given below,
Example:
Find a new representation of the equation 2x2 -xy + 2y2 - 30 = 0 after rotating through an angle of θ = 45°.
Solution:
The given equation and angle is,
$$ 2x^2 - xy + 2y^2 - 30 = 0,\; \theta \;=\; 45° $$
,
To find the value of x and y coordinates, the rotation formula is,
$$ X \;=\; x\; cos(\theta) + y\; sin(\theta) $$
$$ Y \;=\; -x\; sin(\theta) + y\; cos(\theta) $$
Put the x and y values in it,
$$ x \;=\; x’ cos \theta - y’ sin \theta $$
$$ x \;=\; x’ cos(45°) - y’ sin(45°) $$
Simplify the above expression for the solution of the x-coordinate value,
$$ x \;=\; x’ cos(45°) - y’ sin(45°) $$
$$ x \;=\; x’ \left( \frac{1}{\sqrt{2}} \right) - y’ \left(\frac{1}{\sqrt{2}} \right) $$
$$ x \;=\; \frac{x’ - y’}{\sqrt{2}} $$
For y coordinates values,
$$ y \;=\; x’\; sin(45°) + y’\; cos(45°) $$
Simplify it to get the solution,
$$ y \;=\; x’\; sin (45°) + y’\; cos(45°) $$
$$ y \;=\; x’\; \left(\frac{1}{\sqrt{2}} \right) + y’ \left(\frac{1}{\sqrt{2}} \right) $$
$$ y \;=\; \frac{x’ + y’}{\sqrt{2}} $$
