Understanding of principal components of quadratic function f (x) = ax 2 (2b1) x-a-2 transformation.
The straight line ax+b=0, ab is constant and X is variable, but it is also possible that ab is variable and X is constant, and the situation will change, but it is only as meaningful as the equation. When solving problems, this transformation sometimes seems strange and simple. Principal component transformation is actually a transformation, and transformation is one of mathematical ideas.
