Using both the rotation matrices earlier in this lesson and your matrix calculator, find each determinant.

1 and 1 on edg 2020

Step-by-step explanation:

just did the assignment

next question : Find the following determinant by hand.

answer is : 1

Next question : In mathematics, a pattern may suggest a conclusion, but it is not proof of it. Next you will prove that the determinant of a rotation matrix (CCW about the origin) must be 1. Luckily, there is the general rotation matrix you can use.

Answer : cos^2x + sin^2x

Next question : Using trigonometric identities, this can be simplified to

Answer : 1

/next question: In the lesson, you used the following matrices to create reflections

All these reflections resulted in CONGRUENT figures.

next question: Find the determinant of each of these:   - 1

next question: A • At =

 a  b  

cd

 where At is the transform of A. a=1 b=0 c=0 d=1

next question: Repeat this process for the other three matrices. The product of a reflection matrix and its transpose is the identity matrix

Choose the correct choice for the matrix after applying the transformation to the triangle: A

The resulting matrix creates an image that is  to the original triangle.: not similar

Find the determinant of the rotation matrix.

Det R = 1 which matches the determinant for our other translation matricies

Find the product of the matrix and its transpose:  R·Rt  is none of the above
