Not sure what method you're referring to... but one substitution comes to mind: let , so that . Then
This ODE is separable, as
Integrate both sides; on the left, we have
which has a recognizable antiderivative, giving us
so that the solution is
(-2,8) is the image point of A(8,2)
<h3>What is
Rotation ?</h3>
A rotation is a type of transformation which takes each point in a figure and rotates it a certain number of degrees around a given point.
As we know , the rule for rotation of is given by :-
(x,y)⇒(-y,x)
In the above formula (x,y) is the point of pre-image and (-y,x) is a point of image.
Since ,given point of pre-image : A(8,2)
After the rotation of , the image point are :-
(8,2) ⇒ (-2,8)
Therefore,
The image point of A(8,2) is (-2,8) .
