Solve with x under fraction bar = FALSE
Hello,
I tried to write a program which uses the solve function with an function entered by the user. It looks like this:
The result is, that it prints 'FALSE', but only if I use examples with an x under the fraction bar. My example function was (3x^7-x)/(x^2).
Has anybody an idea what I can do to get the right answer?
EDIT: It has do do something with diff, because if I use solve on the function before calculating with it, it works.
An error occurs which says "wrong argument type".

- Code: Select all
Input a,"Function f(x)"
diff(a,x,1)->b
solve(b=0,x)->z
Print z
