Well we really are getting into calculus now! The work you completed in the introduction differential calculus (Chapter 11) gave us the basics of differentiation and antidifferentiation. The complete solutions to Ex11.4 have been posted on the Wiki. Now though we are ready to start using calculus. This brings me to the thing I hate the most about doing maths … graphs! I don’t know why, but if I get too many graph problems to do I just start to loose the will to live! 😦 Now I wouldn’t want to lie to you and say that there is no graphing in the work we are plunging into right now, but there are very few graphs and that can only be good as far as I am concerned. So what is the bad news? None! Calculus is cool! Once you get to understand a few basic rules it makes life so much easier.
Now if you have nothing better to do you might like to look at this short video on how cool and useful calculus can be. (I just want to distance myself from the content though and point out that it was Ms Day who found this video!)
