Teaching maths matrix - Cramer Rules

Update terakhir:

Yes. Tonight got a maths class. 4 students in my class. repeating students. Diploma IT.

  1. teaching them matrix, inverse matrix, finding inverse matrix 2 x 2 and 3 x 3.

  2. lastly is the Cramer Rule. we used this to solve simultaneous equations with x, y and z

variables. the three unknowns. But they have tto be careful with the determinant. if determinant is zero .. then there is no inverse matrix. Get me?

I just ask them to check out my working from 5 sampled questions/ answers. Fill in the blanks similar to Stroud Book - Engineering Maths 1970s. London.

  1. Finally I plan to give them some homework n thats it. So simple.
