Is there a "proper fraction" command, like in TI-Nspire CAS?
Hi to all,
I 'm a graduate teacher and I want to see if I students can use GeoGebra to calculate the derivatives of algebraic expressions.
For example, when I 'm looking for the derivative of f(x)=(x + sqrt(x)) / x²
GeoGebra yields f'(x)=(1 + 1 / 2 / x^(1 / 2)) / x^(2) - (2 * (x + x^(1 / 2)) / x^(3)).
This is very confusing for the students.
How can I make Geogebra yield f'(x)=-1/x^2 - (3/2)x^(-5/2) ?
In other words, how can I make GeoGebra to break the output properly into simple separate fractions (=present the output into a polynomial form)?
In TI-Nspire CAS, there is a command called "proper function" that does this work.
