Question 1

What does a zero determinant of a transformation matrix geometrically indicate?

  • Scaling by a positive factor

  • Reflection about an axis

  • Collapse of the shape into a line or point

  • Rotation

Question 2

In computer graphics, determinants are used to:

  • Compute color palettes

  • Perform geometric transformations (like rotation, scaling)

  • Compress images using JPEG

  • Generate random textures

Question 3

Why is a non-zero determinant important in cryptography (e.g., Hill cipher)?

  • To make the cipher unbreakable

  • To ensure the encryption matrix is invertible

  • To reduce the key size

  • To generate random primes

Question 4

In robotics and control systems, determinants are used to:

  • Encode sensor data

  • Check if the transformation matrices are invertible

  • Design the robot’s body

  • Encrypt control signals

Question 5

In data science, how are determinants applied?

  • To sort data

  • For multivariate statistical analysis and in algorithms like linear regression

  • To generate random numbers

  • To draw graphs

Question 6

How are determinants used in network analysis (graph theory)?

  • To count number of spanning trees

  • To color the nodes of a graph

  • To compress the graph

  • To find shortest paths

Question 7

In structural engineering, determinants help to:

  • Choose the materials (steel or concrete)

  • Solve equilibrium equations for structures like bridges

  • Forecast weather

  • Encrypt building blueprints
