As a Covid project and as a way to stay in touch with her grandson, she is trying to keep up James's math class. That's where I fit it...her math Siri helping to keep her in the passing lane.
I must admit that I am impressed with the Australian math curriculum. Their syllabus for Calculus is very well thought out and should provide students with an excellent basis for future math studies at the university level. Like the Ontario program, many of the lessons are discovery based but unlike ours, they seem to go into more detail and rigor. As far as I'm concerned, that's a good thing. In Ontario, the underlying theme of the curriculum is to give the students the 'big picture" and not worry about the small stuff. In Australia, it would seem the notion is to build a solid understanding of the underpinnings of that big picture.
As well as admiring my sister's passion in trying to revisit something from her distant past, I relish the opportunity to help her with her learning curve. Yes, I do enjoy playing the white knight sometimes.
For those who share my passion for all things math, have a look at my sister's latest request for help. For who don't, best we part ways for now.
Hi Michael,
Hope you don't mind. I find this math fascinating, like a puzzle that has to be sorted out. But I am really lost here, don’t know why.
What is the derivative of y= the square root of x?
All the questions before were done using the formula f(a+h)-f(a) divided by h as h goes to zero. That worked fine.
With this one, the square root of x, the handout explained there is a special trick for finding the answer. The limit is not found by factorization and cancelling (usually the case) but rather rationalizing the numerator.
I’m stumped.
Really appreciate your help call anytime or if you prefer answer online.....xoxo... Yvonne
