How to solve equations using Solver mode

[@TheSadReality12]

You are an absolute legend.

Happy to help!

[@jesuisravi]

what does the lft, rgt on the solver screen mean?

[@ColorMeNette]

Thank you so much! I needed this.

[@장현웅-e1o]

How can you get two roots? For example, equations like x square equals 1. I've tried so much but it always shows only one root

[@harpot678]

Use polynomial. But you probably found out already.

[@startgiving1]

Would you please explain how to use % key using the Casio fx 97 !??

[@981unknown]

Thank you so much ,please can you tell me in some cases we have an equation equal to let us say 0 at 2 different x s let us say at x equal 0 and x equal 2.5 how to make the calculator show both answers ,mine only shows one please help me

[@infinityplusone]

That is usually a quadratic equation and you need to just another steps I have a couple of videos for that on my channel

[@981unknown]

@@infinityplusone thank you so much i needed this for my Ap exam thank you so much

[@birdyplays7107]

is there anyway to find more than one root using solver? for example, x squared minus one, has two roots; 1 and -1. but on the solver, it only shows one of the two solutions.

[@infinityplusone]

The best way to do that is do it by using graphs or quadratic equation solver

[@YourLocalLeo]

great video straight to the point

[@infinityplusone]

Cheers

You are BRILLIANT THANK YOU

[@gcalvaro]

Is it possible the use of units (meters, inches, barrels, etc) in the SOLVER app?

[@infinityplusone]

I don't think so and I am not sure.

[@Rampatuolistani]

When I enter P=A*e^(K*T) to calculator and place values a = 30 k=0.2 t=10 I get syn ERROR from my casio CFX-9850C PLUS same with p=400 A=30 T=3 Should I form the equation differently in my calculator?

[@infinityplusone]

Screenshot to my email or insta please

[@abdulrahmanosama8477]

Hi. What if i had an equation like: xcosx + sinx = 0, and i wanted to solve the value of x How can i do that?

[@shaylamckay1174]

Thank you so much I just got in seventh grade and I was so confused on how to do this on a calculator

[@infinityplusone]

Not a problem!

[@ElitePraetorian421]

Thank you so much! I wish I had known of this earlier hahaha

[@celeschal]

How do I use this to solve for a complex number? I am able to use the simultaneous version with complex numbers but not this equation solver

[@infinityplusone]

Could you give me a question please

[@celeschal]

@@infinityplusone 5iX = 6. I have tried just a simple equation like this but it keeps giving me syntax error, even though complex mode is enabled.

[@manaakidavis4725]

can you do a video on a Chance and Data paper please?

[@ronin6158]

how do you save the equation? I can get to fmem via options, and it shows sto but does nothing when pressed.

[@infinityplusone]

It gets automatically saved to graphs i think

[@ronin6158]

@@infinityplusone no. just worked it: You have to still be in entering equation mode to work, ie: if you hit exe it wont save.

[@detour7102]

Thanks so much, helped a lot

[@infinityplusone]

no worries :)

[@RobRonson]

i always get syn error

[@infinityplusone]

Send me the problem and will have a look at it

[@unclesnappy3555]

This is all good if an individual knows the calculator as well as you do. Too many KZbin instructionals blow through the device explaining things. They need to slow down and take a minute to allow everyone to catch up. Slowly to start "THEN" add in your hyperspeed useage abilities you've learned afterward. Geeze.

[@infinityplusone]

Thanks for the feedback
