To all,
Note a mathematical question per say but one about “shortand” with Mathcad 15.
Is there a way of defining the coefficient of a polynome (say as a vector) and tell Mathcad that I want a full polynome like this: P(x)=a0+a1x+a2*x^2 + …. + an*x^n (= SUM (an*x^n))
I can see the factor and expand commands but cannot find anything that does what I want/looking for.
Thanks
Solved! Go to Solution.
If you want to use it as an operating (calculating) function, then you've already written it:
If you want it displayed as a full-length expression, I doubt it.

thanks. It was just in case there is a "obvious" predefined function. Something like p(x)=polynome(a,x)
I found something in my library of useful functions but the sum will have to do
Thanks to both

Why not?
Those of us constrained to Express don't have symbolics (such as they are.)
That's "Why not!" 😉
Ah, I see.
But the question was about MC15 anyway where there is no express mode.
You may also consider writing a small utility function which turns a vector into a polynomial function.
The example below also shows that the names of formal and actual argument must not be the same.
Of course I would not use a confusing naming like the one shown in a real world worksheet.
