than you so so so much.You don't know how much you helped me.

[@nivshushan9438]

Thanks! Can you please teach me how to do double and triple integrals on this calculater?

[@TheCalculatorGuide]

I am not sure if you can. I will look into a way of doing it, but it might not be possible.

[@farhannoor3935]

Nice vid...knew this before IGCSE anyway...will u post the online master your 991ex course on UA-cam?

[@TheCalculatorGuide]

+Farhan Noor No only previews. The course will be on Udemy

[@danielm1]

Excellent, thanks :)

[@felimconroy2650]

Is there a way to check if integrations are correct using this calculator

[@TheCalculatorGuide]

Only by checking values against your result. This is covered in the course.

[@Alen069]

Wow this is awesome

[@JohnWick-wv3qt]

thanks a lot

[@15october91]

Thank you.

[@finlaywilson8466]

you need to explain from the beginning i have no idea what the difference between radians and all the other option or even how to access them

[@lmc3307]

Then you shouldn’t be doing maths lol

[@aj.baloch2491]

Can you tell me about sciencefatic calculator keys names with this calculator and there blue colour functions so how to use them

[@TheCalculatorGuide]

I will be putting some more previews from my fist course on soon as it is nearly finished...finally. By blue colour, do you mean AC and Del. AC clears the screen or takes you back to the start of a particular process, DEL deletes the last written thing like a backspace.

Why there is range error showing in my calculator??

[@TheCalculatorGuide]

Not sure, but it is usually down to having values in the submitted range that are not valid

[@fadimumoyinoluwa9392]

@@TheCalculatorGuide even my own is saying range error. And I used the same range as yours

[@TheCalculatorGuide]

@@fadimumoyinoluwa9392 Not sure. If you are not too fussed about your settings being altered I would try a reset and then give it a go. See what happens

How to Log differentation

[@TheCalculatorGuide]

You cannot get a result which is in logarithmic form (eg ln2). The calculator will only give these as decimals.

[@omnibrain8]

I get range error on fx classwiz.

[@TheCalculatorGuide]

It sounds like you have to big a range between your start and end. Try with a smaller difference.
