Powerful One Line Calculator - The 21st Century Version of the TI-34
The Victor 930-2 calculator has the following features:
* Trigonometric functions and their inverses
* Rectangular/Polar Conversions
* Degrees/Degree-Minute-Second Conversions
* Logarithms, Power, Exponential
* Single Variable Statistics
* Base Conversions with Boolean Functions (AND, OR, XOR, XNOR, NOT)
* Constant Calculations
* Fractions
The keys have the same mapping as the original Texas Instruments (one line) TI-34 from the 1980s and 1990s. There are some keys and functions that are labeled differently:
Victor 930-2: [ X→M ], TI-34: [ STO ]
Victor 930-2: [ M+ ], TI-34: [ SUM ]
Victor 930-2: [ X←→M ], TI-34: [ EXC ]
Victor 930-2: [ INV ], TI-34: [ 2nd ]
Victor 930-2: [ DATA ], TI-34: [ ∑+ ]
Victor 930-2: [ DEL ], TI-34: [ ∑- ]
The Victor 930-2 has a bigger and clearer numeric display and an on-off switch.
Constant calculations is something that might be an overlooked feature on some of these calculators, so let's take a look at how it works. This applies to both the Victor 930-2 and the TI-34.
Constant Calculations
For selected two argument functions, you can repeat the calculations on the second argument by entering different values and pressing the equals button [=].
A (op) B [ = ]
C [ = ] ( C op B )
D [ = ] ( D op B )
...
op: +, -, ×, ÷, y^x, x√y, AND, OR
Example 1:
f(x) = x × π, x = 4, 3, 3.8
4 [ × ] [ INV ] [ EXP ] (π) [ = ]
Result: 12.56637061
3 [ = ] ×π is stored in memory
Result: 9.424777961
3.8 [ = ]
Result: 11.93805208
Example 2:
f(x) = x^2.5, x = π, 10.2, e
[ INV ] [ EXP ] (π) [ y^x ] 2.5 [ = ]
Result: 17.49341833
10.2 [ = ] ^2.5 is stored in memory
Result: 332.2771137
1 [ INV ] [ LN ] (e^x) [ = ]
Result: 12.18249396
Example 3:
B can be a multi-step in constant calculations.
f(x) = x ÷ (4^2 + 3), x = 10, 20, 50
10 [ ÷ ] [ ( ] 4 [ x^2 ] [ + ] 3 [ = ]
Result: 0.526315789
20 [ = ] ÷(4^2 + 3) or ÷19 is stored in memory
Result: 1.052631579
50 [ = ]
Result: 2.631578947
Fractions
You can enter fractions and calculate with fractions. However, you can only convert between fractions and decimals if you start with fractions in your calculations. The calculator has a limit of 10 digits between the whole part, numerator, and denominator.
Keyboard
The keyboard is OK. I like the contrast between the black background and the font better on the Victor 930-2.
I am irked by the protective case, as it is difficult to take the hard shell case off once the calculator is locked in place. I prefer the slide case of the TI-34. I may not cover the 930-2 and use a case or the box to protect the calculator.
Verdict
If you are looking for a TI-34, consider the Victor 930-2 as it is an updated version. It does the job. Again, I wish the hard shell case was easier to work with.
