Blows away the manual that comes with the calculator
It is not saying much to say that this is MUCH better than the manual for the calculator. That thing is very difficult to navigate and even if you can find the discussion of what you are trying to do, trying to follow the steps is not all that easy. This walks you through how to do all of the main operations. It is great for figuring out how to use derivatives, integrals, matrices and vectors. Because this is capable of algebraic symbology some teachers will not let you use it on exams. It can basically give you the answers to the problems (if you know how to input the information correctly, which this walks you through step-by-step) but will not show the work. So some teachers do not care if you use it on exams because you can only get the points if you show your work.
What I love is that he will walk you through all the buttons to push to input the functions to perform whatever operation you want. Entering integrals and differential equations can be especially...
Great continuation of volume 1
I loved volume 1 and volume 2 is no different. I can't recommend this product enough. It unlocks the ti-89 calculator. The tutorials are done on a ti-89 titanium but they all look like they would apply to the slightly older TI-89. As I said in my other review of volume 1, having watched these tutorials was like having a good car and then only later finding out you had a trunk, back seats, and that the windows rolled down.
The TI-89 is, at present, the among most powerful calculator allowed into most exams. Many of its features are a bit obscure so having a full understanding of this tool can only help make things easier.
Good Learning Aid
The manual that came with my TI-89 was a bit confusing for me. These DVD tutorial videos were just what I needed to learn to use this wonderful calculator. Well worth the cost. Tip - Get these videos before you start Trigonometry or Calculus :)
