Question 1

Could this calculator do indefinite differentiation and integral?

Accepted Answer

Yes, but first you need to upgrade the o.s. to fx9860gii and add two apps: Algebra and CAS, downloadable from tiplanet (a well know site in French, largely devoted to Casio calculators).

CAS is brilliant for differentiation; coping with quite complicated functions, e.g. x^x. CAS also expands brackets, coping with binomial expansions, where n is a positive integer, but doesn't recognise complex numbers, so it can't cope with simplifying (z-(3+4i))(z-(3-4i)) correctly. It can do indefinite integration but only very simple integrals based on x^n.

Algebra also does differentiation using symbolic logic, but not as well as CAS. It is, however, much better at indefinite integration and can cope with many integrals set where they are soluble 'by parts'. It also expands and simplifies algebraic expressions and recognizes complex numbers. As an example, (Z-(3+4i))(z-(3-4i)) is simplified correctly, to z^2 - 6z + 25, using the 'Simplification' option. It also has a number of high-end features like Taylor Series, Curl etc.

Do be mindful that this isn't the best calculator to use for calculus. The T.I. NSpire CAS, for example, leaves it for dead in this respect. It can give the correct integral, using symbolic logic, in any situation applicable to a-level maths and further maths. Furthermore, it'll give exact answers in terms of e, ln, pi, etc to definite integrals and also for differentiation. The fx9860gii o.s. will do this only occasionally!
