fx-115ES+2: Solving for x Using Multiple Methods

[@marcos1585]

I have a materials engineering test tm and this calculator has been with me through a tough semester, I never knew it could do this and thanks to you I’ll get a A on my test

[@bahaah5218]

Thank you for the clear and easy explanation

[@AprendizDeLoQueToca]

I love Casios 🙏🤗

You are welcome!

GREAT VIDEO. THANKS FOR YOUR TIME!!!

[@Garfield_633]

Omg I didn’t know that I had to hit the = after the solve to get the x I was so confused! But now I get it, thanks for explaining!

[@CasioEdTech]

This is a pretty common area of confusion for the SOLVE feature, which we've noted for the R&D folks. ^Dave

Just to let you know. The Casio 115ES+ is a great machine. I have one myself. However, the ClassWiz is a little more capable. You can actually use the linear solver feature in conjunction with the numerical integration and differentiation functions. On the 115ES Plus, you can’t use them together. It is not an issue for high school students and most engineering. If you are in advanced engineering classes, some applications are only doable with the ClassWiz.

no matter what equation i put it always says "syntax error", what do i do?

[@bryanacevedo4724]

What a lifesaver, thanks

[@CutinChai]

I get an error when I am using complex (i) equation to solve for X.

[@bertalev2010]

I copied your example to my calculator for the 3rd method using the equation mode and I am getting a "Math Error". Please help?

[@DrGatoluche]

Thank you very much. I do wonder, what is this graphical representation of the calculator you have? Is it like a "calculator emulator" of sorts?

[@whitevinegar4168]

We want this model in south east Asia. Why this model is available only in north America?

What is the start and the end

[@ChaoticBad]

What if there’s 2 X answers? How will it show the 2?

[@CasioEdTech]

I am not quite sure I understand the question?

[@chocken4867]

@@CasioEdTech They mean for example in a quadratic equation, you get two answers. The calculator only shows one. How do you get the other answer?

[@alfredoramirezmorales5912]

@@CasioEdTech I have the same question, how to see all the multiple solutions using the COMP mode, for example for a rational exponent?

[@eagle93616]

I tried to solve x for this equation e^(3.14*X)=100/30. X should be around 0.38, however by using the calculator, it kept telling me the result is 0.24... wondering where I did it wrong...

[@TeamCobes]

I don't know why yours did that, it worked for me when I copied yours. Maybe you typed it in wrong?

[@stevestewart3816]

So if I had 6=-8/x how would I solve that with the calculator?

[@IntelligentProbe]

(-8/x)-6=0
