Log graphs

Sosmaths has some good lessons on exponential and logarithmic graphs at http://www.sosmath.com/algebra/logs/log4/log42/log42.html and further information on logarithmic graphs at http://www.sosmath.com/algebra/logs/log4/log42/log422/log422.html. See http://www.purplemaths.com/modules/graphlog.htm for further information on logarithmic and square root graphs. Another useful site that looks at translating the logarithmic function and the relationship between logarithmic and exponential functions is http://www.themathpage.com/aPreCalc/logarithmic-exponential-functions.htm, although you need to be careful with the notation, it is not rendered well on my browser. Another applet at http://www.uncwil.edu/courses/mat111hb/EandL/log/log.html allows you to investigate the relationship between the exponential function and the logarithmic function.

Square root graphs

The relationship between parabolas and square root graphs can be found at http://www.themathpage.com/aPreCalc/graph-of-parabola.htm#parabola, and http://www.purplemaths.com/modules/graphlog.htm has information on logarithmic and square root graphs.

Further Resources lion

The Mathematics Learning Centre holds workshops at the beginning of each semester. Keep an eye out for dates.

There is a Massey Universtiy Site that covers most topics well and is worth having a good look at. There are also some quizzes at http://webct-ce.massey.ac.nz/SCRIPT/tsamith1/scripts/serve_home that can help you identify problem areas.
