Glenney's Scribe-aler

^(Get it? Scribe-aler... scribbler?... not very funny I guess? hey, at least I tried :P)

This morning was better than it usually is. With more enthusiasm and energy, this year's going to be pretty good. I guess everyone's getting a lot more used to each other and it's not so quiet whenever Mr. K asks us if we get what he's saying. The morning started off with our usual challenging problems that sometimes makes us think until our head hurts :S. As soon as we all talk about the problems the first thing Mr. K always says:

Remember that :)
Mr. K's trying to plant that in our heads for the rest of lives! It'll be worth it though in the future. In university, the prof's going to ask what is a logarithm and you'll stand up, and say.. "A logarithm is an exponent!"
After a very interesting list of mascots, we finally made our decision with "The Prince of Calculand" featuring our very own Prince. I guess I'll be one of the first to say congrats! haha. It was pretty much a unanimous decision and I think our story plot's going to be very interesting.
Back on track with the problems, we learned that sometimes an extraneous root may appear. With this showing up, we had to remember to always check if our answer can fit the equation properly. In this case, -10 or any other negative number cannot be true because any number to any exponent cannot equal a negative number. The number must be positive and cannot equal 0 or be a negative number.
Near the end of class, we learned about the graph: f(x)=1/x and how it never touches the x or y axis'. No matter what number you substitute for x, whether it be a fraction or a large number, it'll never touch.
I guess this wraps up my daily blog, see you all tomorrow :)
Up next... Jay :D
