Systems of simultaneous equations are intriguing.
They are used to identify points that the equations have in common (in this case, an x and a y value). Interestingly, there are a number of ways to solve equations simultaneously. The two primary methods that are first learned in middle high school are substitution and elimination. In time, mathematics students also learn about the use of determinants and matrices as well (not to mention vectors, etc.).
My plan (at this stage) is to address these four key methods/topics on this website.
How I wish you could be my professor – I have been having a consistent problem with the chain rule for what seems like weeks. I couldn’t grasp it at all. The first couple minutes of your video – it all instantly clicked for me. You are a life saver and a wonderful teacher. Thank you so much for your explanations!!!!!!!
