The set op function on the TI 36X PRO can be used to take the square root of a complex number. I've done it. Once you set it up to take the root of, simply store a complex number in X and hit 2nd + op. Op = sqrt(IxI) * < angle (X) / 2. You can also set this function up to do the hyperbolic sine of a complex number. Works great for transmission line parameters.
Cool use of the OP function and shows you are clever with roots of complex numbers. If you did a lot of this sort of thing, a programmable calculator like the DM42 might be perfect (though pricey!).
@@scottcollins7513 the DM42 isn't allowed or approved for my professional engineering exam, plus I really like the menus and functionality of the TI calculators. I don't think Casio has a set op function, but I'm curious if Casio has a similar feature.
@@soccerstudut I see - I think you should stick w the TI-30X Pro MathPrint. It does everything you need and as an engineer you will be able to afford and justify $20-25 more for the right device.
@@scottcollins7513 my thoughts exactly. I love the TI 30X PRO MathPrint. Not sure why it's not sold in the US, but I reached out to someone in TI to ask why. I recommend the TI-30X PRO MathPrint for anyone taking the PE Exam.
What is also interesting some of the models years ago could handle more complex math. From years back, the old TI-54 could handle the expression “4.7*square root of ( 4+2i).” You have to go to a graphing calculator in most instances to be able to solve this. The TI-36XPRO, Casio ClassWiz and Casio FX-115ES Plus all give an error message. Try it on the DM 42 and see if it will give an answer. 1.3686+0. 1355i. The old TI-54 could do it.
The DM42 is able to compute this, though I am getting 9.673+2.284i. It is interesting that today's scientific calcs do not handle this when old ones did.
Mr. Collins. This is a little off the subject but have you seen some ads on RU-vid lately from some local companies online selling new TI-89 Titaniums for $40 and new TI-84CE’s for only $50? It seems quiet far fetched to me. These companies are claiming 100% authenticity. This would seem like a scam to me. I have never heard of anybody, including Amazon, selling those calculators for so low in new condition.
