I noticed that in your blog, you were happy to see that it could deal with complex numbers, even with trigonometric functions. I am not having success with that...how do I get this to work? Unfortunately, trig functions of complex numbers no longer work. This probably a side result of the new OS (3.10.0212). I must have written my review before I upgraded the OS. I will note this in my review, thank you for catching this! Why Casio why? Trig functions with complex numbers will now have to use the work around (there are others): sin (a+bi) = sin a cosh b + i cos a sinh b cos (a +bi) = cos a cosh b - i sin a sinh b Thankfully the ln and e^x functions still can work with complex numbers. |
