In complex analysis, a function preserves angles if and only if it is analytic or
anti-analytic the conjugate of an analytic function. In the present chapter, we will deal
with the transformation and conformal mapping, let us start this chapter, by introducing
the meaning of the word "Conformal", then introducing some basic definitions for both
mapping and transformation. Question: what does it mean by the word conformal? The
answer is quite simple, the word conformal means preserving angle of the shape after
transformation at a certain point.
Keywords: Bilinear transformation, inverse transformation, linear transformation,
power transformation, transformations.
