Calculate Phasors with TI CX CAS & TI 89: A Comparison

It may take some time to get used to it.In summary, the TI-NSpire CX CAS can handle equations with complex numbers, so it should be able to calculate phasors. However, if you are not familiar with the TI-NSpire, it may be difficult to use in a few days for your test.

Hi guys

Can I calculate phasors in a ti cx cas as simple like in a ti 89.
In a few days I will need to calculate them in a test, so I need to buy a ti nspire cx cas or ti 89. I think ti inspire cx cas can manage ecuaciones with complex like 89 does, but I can't find how to calculate phasor simple.

sorry for the poor english.

regards

Hi gonzalol, the TI-NSpire will handle complex numbers (like a+bi), so I am sure you will be able to calculate phasors.

However, if you have never used a TI-NSpire and your test is in a few days, it might be difficult for you. The TI-NSpire has different controls and a different layout than the TI-89.
 

1. How do I calculate phasors using a TI CX CAS and TI 89 calculator?

To calculate phasors with a TI CX CAS or TI 89 calculator, you will need to use the complex number feature. This can typically be accessed by pressing the "2nd" or "mode" button on your calculator and then selecting the complex number option. From there, you can input your phasor values using the format a + bi, where "a" represents the real part and "bi" represents the imaginary part.

2. What is the difference between using a TI CX CAS and TI 89 for phasor calculations?

The main difference between these two calculators for phasor calculations is that the TI CX CAS has a built-in phasor mode, while the TI 89 requires you to manually input complex numbers. Additionally, the TI CX CAS has a larger screen and more advanced features, making it more user-friendly for complex calculations.

3. Can I use phasor calculations on both AC and DC circuits?

Yes, phasor calculations can be used for both AC and DC circuits. However, phasors are most commonly used for AC circuits because they represent the amplitude and phase of a sinusoidal signal. In DC circuits, the use of phasors is not as common, but they can still be used to represent complex impedance.

4. What are some common applications of phasor calculations in scientific research?

Phasor calculations are commonly used in fields such as electrical engineering, physics, and telecommunications. Some common applications include analyzing AC circuits, studying electromagnetic waves, and designing communication systems. Phasors are also used in signal processing and control systems to analyze and manipulate signals.

5. Are there any limitations to using phasor calculations with TI CX CAS and TI 89 calculators?

While these calculators are powerful tools for phasor calculations, they do have some limitations. One limitation is that the calculators can only handle a finite number of significant digits, which may affect the accuracy of the calculations. Additionally, the calculators may have difficulty handling extremely large or small values, so it is important to check the results for reasonableness.
