RE: TI36X Pro—Replace the batteries or just get a new one?
I've done a few speed comparisons between the TI30X Pro MathPrint, the TI36X Pro (or TI30X Pro MultiView), and one of their greatest rivals, the Casio fx991EX ClassWiz.
For a measurement technique, I basically filmed the calculations on my phone and measured the time using video editing software. There is a little bit of wiggle room because the calculator screens take some time to refresh, but I estimate my timings to be accurate to about ±0.1s.
Test 1  classic summation based benchmark
This is the classic summation based benchmark from http://www.hpmuseum.org/forum/thread9750.html with n=1000. \[ \sum_{x=1}^{1000} \sqrt[3]{e^{\sin(\tan^{1}(x))}} \\ \begin{array}{cr} \text{Model} & \text{Time (s)} \\ \hline \text{TI30X Pro MP} & 103.7 \\ \text{TI36X Pro} & 257.9 \\ \text{Casio fx991EX} & 106.9 \end{array} \] Test 2  Eddie Shore's \(x^{2}\) summation test This is a summation test from Eddie's speed test video: https://youtu.be/39tcSQBakMo?t=156 \[ \sum_{x=1}^{500} x^{2} \\ \\ \begin{array}{cr} \text{Model} & \text{Time (s)} \\ \hline \text{TI30X Pro MP} & 19.6 \\ \text{TI36X Pro} & 37.4 \\ \text{Casio fx991EX} & 22.4 \end{array} \] Test 3  Eddie Shore's numeric solver test This is a numeric solver test from Eddie's speed test video: https://youtu.be/39tcSQBakMo?t=109 \[ \text{Solve}\ e^x + .2x^3 = 3\ \text{for}\ x \text{.} \\ \text{Initial guess:}\ x=10 \text{.} \\ \\ \begin{array}{cr} \text{Model} & \text{Time (s)} \\ \hline \text{TI30X Pro MP} & 1.7 \\ \text{TI36X Pro} & 5.5 \\ \text{Casio fx991EX} & 1.6 \end{array} \] Test 4  Eddie Shore's \( \frac{\sin(x)}{x} \) integration test This is an integration test from Eddie's speed test video: https://youtu.be/39tcSQBakMo?t=11 Note that the actual test that Eddie ran (and repeated by me) has a different upper limit than that shown on the slide. \[ \int_{.001}^{.6} \frac{\sin(x)}{x} dx \\ \\ \begin{array}{cr} \text{Model} & \text{Time (s)} \\ \hline \text{TI30X Pro MP} & 0.9 \\ \text{TI36X Pro} & 3.0 \\ \text{Casio fx991EX} & 0.9 \end{array} \] Test 5  Eddie Shore's \( e^{x} \) integration test This is another integration test from Eddie's speed test video: https://youtu.be/39tcSQBakMo?t=38 \[ \int_0^{100} e^{x} dx \\ \\ \begin{array}{cr} \text{Model} & \text{Time (s)} \\ \hline \text{TI30X Pro MP} & 2.5 \\ \text{TI36X Pro} & 5.7 \\ \text{Casio fx991EX} & 3.4 \end{array} \] Test 6  VBlogMag's \( e^{x^3} \) integration test This is an integration test from VBlogMag's calculator benchmark video: https://youtu.be/DHRsvSTGiBc?t=584 \[ \int_0^6 e^{x^3} dx \\ \\ \begin{array}{cr} \text{Model} & \text{Time (s)} \\ \hline \text{TI30X Pro MP} & 8.6 \\ \text{TI36X Pro} & 89.3 \\ \text{Casio fx991EX} & 24.4 \end{array} \] Conclusion On the whole, the TI30X Pro MathPrint is significantly faster than its predecessor (as expected), and slightly faster than the rival Casio fx991EX in most tests. The result from VBlogMag's integration test has a surprisingly fast time for the TI30X Pro MathPrint (compared to the other two calculators), but I double checked it. (The TI integration tests were performed using their default epsilon setting.) — Ian Abbott
