Hi again, thanks for all the help with my last question but now I am stuck
with another problem if anyone would be so kind enough to help.
I am looking for a way to check equations, for example, the derivative of
((x^3 - 4x + 3)/x^(4/3) is (5x^(10/3) - 8x^(7/3) - 12x^(1/3))/(3x^(8/3))
when calculated via hand but is (3x^2 - 4)/x^(4/3) - 4(x^3 - 4x +
3)/(3x^(7/3)) when put through mathematica. What I would like to do is if
there is any way to equate the two and see if the statement is true because
obviously it can look like two completely different answers (to a student)
when they are in fact the same.
Another example would be, is there any way to check if E^(:ii:Pi) = -1 was
true (at least according to the Euler-Moivre equation), using Mathematica?
I tried using the "Check" command but I don't know what two arguments there
are (I tried putting in lhs,rhs but I just got the former as an output).
Thanks in advance,
