Hello,
I’d like someone to help finding the solution for 4 exercises from Matrix Analysis &Applied Linear Algebra, text book by Carl D. Meyer.
I want a detailed solution with step by step instructions shown and explained in a video , if there is more than one solution please explain both of them.
I have provided screenshots of the questions, in addition to the textbook if you don’t have it.
Please do not bid unless you are 100% familiar with the topic, and able to deliver a detailed step by step solution, and record a video (Decent quality and clear) while solving it as if you are tutoring, teaching or giving a private lesson.
I expect the answer to be explained handwritten on a paper, board, or note taking app like One Note, Notability or similar.
