Derivatives and Differentials

Just one funny point, I spent a while finding the derivative of this equation when I could have just remembered that: y = mx + b Opps...

Also, the function

we did in class on the calculator on the Smartboard...

When Mr. Flint zoomed in on the point (0, 0), the graph became a straight line. Although the slopes are heading toward zero as x -> 0, if you changed the y-axis the graph would no longer be a straight line, but curved. So the only true way to discover if a function is differential at any point is through algebra.

I think when trying to find the limit of an equation dealing with +∞ or -∞ it is often easier to solve by drawing out the different components of the equation for example this function:

I wish that we learned what all this is used for and how to apply in various tasks.
