Multiplicative Identity: Matrix of 1 0 0 1
Multiplicative Inverse: Found by flipping a and d and making b and c negative, Then multiply the 1 over the determinant
Transformation Notation: An equation that compares the difference between another equation which shows a vertical transformation
Vectors: Show translations
Magnitude: The size of a vector

Finding multiplicative inverse: Find determinant of  the matrix and then multiply 1 over the matrix by d, -b, -c, a
Find determinant: ad-bc
Solving matrix equations: abcd times xy=ef]]> 2017-03-15 17:57:25 UTC https://padlet.com/haberfieldl8432/e9gq3bagrs8j/wish/160335286 Concepts haberfieldl8432 https://padlet.com/haberfieldl8432/e9gq3bagrs8j/wish/160345289 Prove quadrilaterals: With side lengths/slopes
Find the determinant: multiply a and b and c and d and subtract
Creating a Vector: End to end or Parallelogram Rule.
Parallelogram: From the origin make vector a and b. Attatch vector a onto b and b onto a to create a parallelogram. From there, form the diagonal created by one point and the origin. This line is the new vector.c]]> 2017-03-15 18:30:21 UTC https://padlet.com/haberfieldl8432/e9gq3bagrs8j/wish/160345289 Example Problem haberfieldl8432 https://padlet.com/haberfieldl8432/e9gq3bagrs8j/wish/160347026 What is the determinant of the matrix: [4 5 ]
