A) Linear transformation

B) Bilinear transformation

C) Non-linear transformation

D) None of these​

Answer 1

Answer:

a !!!!!!!!!!!!!!!!!!!

Answer 2

The correct answer is option (A) Linear transformation.

Explanation:

• The finite Fourier sine and cosine transforms and their inverses are all Linear transformation.
• A linear transformation refers to a function from one vector space to another that respects the underlying (linear) structure of each vector space.
• A linear transformation is also known or called as a linear operator or map.
• The two vector spaces must have the same or identical underlying field.
