comparisations
(OP)
Is it possible to solve comparisations in mathcad?
ex : x³ +5x² +x +7 = 0
Thanks a lot

where ordinary BASIC code can be typed in any word processor and the results are typed back into the document.
I would enter the function:
FX = "(x^3 + 5*x^2 + x + 7)"
Then I would find the high-low range of roots:
graph(FX, -10, 5)
(the results of the "graph" function can't be posted here)
Then I discover there is only one result:
RES = bisect(FX,-7,-5,.0001) := -5.0748

RE: comparisations
f(x) := x3+5x2+7
make a guess
x:=-1
Use the root function
R:=root(f(x),x)

There are other examples that could be useful for your purpose.
