The roots of a function are when its value equals zero; depending on the function, it may have several roots.
This video showcases the root and polyroots functions in PTC Mathcad Prime in order to numerically solve for roots of functions.
The "root" function will solve for roots one at a time. You can apply a guess value or the root within a range you provide (bracket values). Make sure Mathcad labels it as a "keyword".
The "polyroots" function will find the roots of a polynomial all at once. This is useful for polynomials of several degrees. In Mathcad Prime, you'll need to input the coefficients of the polynomial. Tip: Use the "coeffs" keyword to produce a vector of all of the coefficients of a polynomial.
The polyroots function is a premium feature in PTC Mathcad Prime, requiring a full license, or one of our 30-day free trial licenses that you can install at [ Ссылка ] . You can easily solve for all of the roots of polynomials you encounter with the power of Mathcad at your side, so download the trial today!
