I want the roots of a function using Mathcad

I want the roots of a function using Mathcad

(OP)
Hello Everyone,

Is there a way in mathcad to obtain the roots of a function f(omega)=0? I am doing it at the moment by first plotting the function and then searching for the places where it is equal to zero. But how do i solve the function directly without first plotting it?

Thanks!
Jimmy

I found a way around this. Thanks!

I use the root function.

This is what I did using the polyroots function.

If I have f(x)=x^n+k1x^(n-1)+.....+k0 and I want the solution for f(x)=0

I first find the coefficients of f(x) using

G=f(x)coeffs,x------->

The coeffs --------> is obtained by using coeffs under Symbolic and the x is added by using the "comma" key on the keyboard. With the coeffients defined:

r:=polyroots(G)

r=
would give you the zeros of the function f(x)
