good day to you all
i'm so happy i found this forum
i'm learning differential equations course and i purchase casio fx-991ES
and now i don't really know how to use it to my propose
i need to do for now 3 things : integrals , derivative and find fractions in polonium

so for the first thing this is the equation i need to solve :

like you can see i need to do integral to both sides and i see in the fx there's the integral button but i tried and tried and i can't figure how to do it....

for the second thing i need to find fractions to some poloniums like in this 3 examples : (i all ready did it with out the fx but i want to be able to use the fx to find this fractions)


for the last thing i need is to solve derivative like in this example :


tanks a lot for all of you

i just found out now that this calc don't have symbolic and only numeric !!!!!
i can't believe this...
is there something i can do?
and also if someone can help me find other good calc in the same size that can do symbolic

There are models called classpad and FX. Personally I opted to not have a CAS calculator, although it can be installed as software on my FX-9860G/GII.

Check out Wolframalpha.com, I use it occationally to search for stuff when I can't figure things out (Press show steps):

thanks
is the FX-9860GII and the FX-9860G can help me do symbolic integrals , symbolic derivative and find fractions in polonium ?
i need do be able to do the examples in my first post
thanks
