Hi everyone,
I'm a week behind schedule but I'm trying to get things back on track with my social media platforms this week!!
In today's video, we're looking at the inverse matrix. Have you heard of it before? When we talk about inverses, you may need to flashback to arithmetic operations to understand this concept of the inverse matrix.
🙃🤓😯
An inverse refers to a mathematical operand, one we can use with another operand to perform a specific operation and obtain the identity as the result.
When performing multiplication of matrices, the inverse is utilized to help with solving for unknowns in matrix equations. You'll see this more specifically when we work with Systems of Linear Equations (our topic for this week!!)
Here are some of the important take-aways from this video to assist you in focusing on the main points relating to the inverse matrix:
1. The type of matrices which have inverse matrices versus those which do not have inverses
2. Identifying matrices which have inverse versus those which do not
3. The process of obtaining the inverse matrix
If you enjoyed this video feel free to leave us a like, some feedback in the comment section and share it with your friends! Be sure to return for the final lesson in our matrix journey: Systems of Linear Equations!!

When we're through with all of this look out for the past paper tutorial to learn how to approach these types of questions, apply your knowledge and solve them with ease!!
Study sessions aren't working out? Just don't have time for attending extra hours of yet another class for lessons?
Take a look at my Student Mastery Series which will be updated twice a month with tips I'd strongly recommend for my students which will guarantee their improvement!! You just need to know which one works best for you and use it!
