TI has made the newly designed sliding cover much more secure than the old TI design (TI-83 plus, TI-86, TI-89 regular), whose sliding cover was not very secure and became looser over continued use. (Besides, I believe most high school math teachers ban the TI-89 on tests) This calculator can also run programs in its Flash memory, which can be downloaded from the TI website.Ī USB cable is included standard. If you don't know what a derivative or an integral is, then save your money and buy a TI-84 instead. This calculator is NOT meant for high schoolers who are taking algebra, geometry or trig classes. First of all, it is more suited for advanced math, such as calculus and beyond. This calculator is unbelievable in its features and power.

For calculus and beyond, perfect! Anything below calculus, this is too much!, JBy D.īezboruah (Irvine, CA) After using a TI-83 Plus calculator for the last 5 years, I decided to upgrade to the TI-89 Titanium. Overall this is a great calculator - I recommend it. However, I'm sure that with more use it will wear in. My only complaint is that the cover does not initially slide on and off easily. All these features plus copy and paste ability make this calculator nearly perfect. This feature allows you to easily see the expression that you typed in. Yet, the most useful feature of this calculator is probably the 'pretty print' feature which displays expressions as you would normally write them on paper. Zhizn kotoruyu vi rodilisj prozhitj knigu. I also found the 'exact mode' very useful (exact mode will give you exact answers rather than decimal approximations). One of the nicer things about this model (compared to the TI-89) is that it has USB connectivity (cord included) for installing applications and transferring data.Īnother nice thing is that it also supports connectivity to older model TI-89s via the old I/O port which is right next to the USB connector. One of the other things I found helpful was the TI-89 Titanium's ability to plot direction fields using different algorithms (including Euler's method). Apparently I gave it an evil look or something though, as the LCD cracks. In my electrical engineering class, and I know it would have made chemistry easier in the past.

After taking calculus and learning about limits, derivatives, integrals, infinite series, Taylor series, differential equations, and multivariable functions, I decided that I would look for a calculator which was capable of symbolic computation.
