Power series representation for the function calculator

In low cost they provide good services, i'm having a hard time in understanding the discussion, but thanks to this app. A really great app it has helped me solve some hard maths problems I couldn't crack myself, worth the price if you can handle it.

This helped me so much on my math classes, solving exercises with the app actually helped me learn more than i did in class haha. Very efficient and effective, user experience is comfortable and easy for us new users.

Otherwise this application is very remarkable. The stuff that it unlocks is some extra explanations and animations, but you can still do everything else for free, amazing app did homework that would've taken 2 hours took me 5 minutes.
