Casio FX-9860G Slim Graphic Calculator Questions & Answers
I cant get my graphs
I believe it has to do with your angle unit. If you angle unit is set to degree and your default window dimensions are -10, 10, then the sine function will look like y=x ( straight line) and y=cos(X) is approximately 1 in that domain.
Your solution is one of the following.
Use degree as angle unit, but change the window dimensions for x to -180 to 180 and the y-dimensions to the interval -1 to 1.
Use the radian angle unit and leave the Xmin-Xmax interval -10 to 10.
How can you change the
Press SHIFT MENU to bring up the setup screen. Use the arrow keys to move to the "Angle" line and press the function key for the desired angle mode.
How do i solve negative
-15x^4 / 3x = -5x³ for x 0.
You should be able to figure this out without having to resort to a calculator. Note the "for x 0"... the two functions are identical everywhere, except the -15x^4 / 3x version is undefined for x = 0 (3 times 0 is 0 and you cannot divide by 0). The function has a "hole" at this point. -5x³ does not suffer from this defect, for x=0 it simply evaluates to 0, so you have to mention this fact to make it proper.
How do i do prime numbers on the NEWYES NY-991MS calculator and CTIFREE fx-991ES PLUS calculator?
The NEWYES NY-991MS and CTIFREE fx-991ES PLUS calculators do not have a dedicated "FACT" button like the Casio FX-83GTX. However, you can still find prime numbers on these calculators.To find prime numbers:NEWYES NY-991MS:Press the "MODE" button.Choose "PRIME" from the list of options.Enter the desired number and press "=" to check if it's prime.CTIFREE fx-991ES PLUS:Press the "MODE" button.Select "TABLE" or "TABLESET."Input a starting point and an ending point, then observe the table for prime numbers.Although the techniques may vary from those used on the Casio FX-83GTX, they prove to be effective for prime number calculations on the designated calculators.
Casio QT-6600 kitchen printer stop working.
Is there lights on, on the printer? Does it have a receipt paper roll in it?
You can do a Power Cycle of the Terminal and the Printer. Unplug the printer for the wall socket. Remove the data socket, replace the data socket making sure the connection is tight.
Disconnect the terminal from the main power, and count to 20. Plug the terminal back in.
Now go to the kitchen and plug the printer back into the mains.
The reset should fix it. The rest is in the manual, which I told you earlier today. Yes it is complicated and you may have a network switch if you have multiple terminals and possibly a computer joining everything. If you find that too complicated, call the company that sold you the unit and tell them to bring a new ticket printer with them 'just in case'. That type if ticket printer is fairly specialized, but they are common. They normally don't charge for that type of help
In the manual under Remote Printer Control.
