# Can a casio fx series do this operation?

"Calculators stackexchange" doesn't exist, so I guessed this would be the right place to ask. Can a calculator solve $-0.2 \cdot e^{-0.06-4.2i}$?

Or any $e$ to a complex for that matter. I've been solving this with Wolfram Alpha or Matlab when in a project, but I'd like yo know if is there anyway to get it done in a calculator.

• Can you please share the answer you expect from the expression? – Jem Eripol Sep 1 '17 at 3:10
• How do you enter "i" ? – Solar Mike Sep 1 '17 at 4:31
• @SolarMike, you change the calculator mode into "complex mode" by pressing mode then 2. – Jem Eripol Sep 1 '17 at 5:16
• Is there any reason other than tests in school where a calculator is prefered over a computer or a smartphone? I mean school requirements hook you to calculators but in reality thats a skill you should get rid of as soon as you leave shool. – joojaa Sep 1 '17 at 5:39
• @joojaa some of us when there is something to calculate will (still) automatically reach for a calculator and, personally, I find i can complete even complicated calculations / problems long before some people have had the computer boot, they log-in and then run the program etc... But your preference.... – Solar Mike Sep 1 '17 at 9:24
