Here’s a brief introduction of iMathGeo’s calculations capabilities:

iMathGeo can :

simplify every literal expressions.

Linearize every literal expressions.

do some differential calculus.

Substitute every literal expressions with other expressions or numbers.

manage variables.

Transform each fraction in decimal number in an expression.

calculate with Matrices (like jordanize a matrix, get the eigen vectors, determinant, etc...)

solve equations or inequations.

solve linear systems or non linear too.

factorize expressions.

calculate limits.

calculate infinite or finite sum or product.

calculate integral,double integral and get primitives etc.

etc...

You can easily manage many calculations together.
