If you get a valid answer, that is where the function intersects the horizontal asymptote, but if you get a nonsense answer, the function never crosses the horizontal asymptote. ...

WebMar 31, 2024 · 2. Set the denominator equal to zero for fractions with a variable in the denominator. When finding the domain of a fractional function, you must exclude all the x-values that make the denominator equal to zero, because you can never divide by zero. So, write the denominator as an equation and set it equal to 0. [2] WebFigure 1 – Roots of a function For example, the formula =BRENT (B3,L3,L4) in cell L5 finds the root -4. The same root is found when a = -5 and b = -2. Here cell B3 contains the formula =A3^3+3*A3^2-6*A3-8. The formula =NEWTON (B3,O9) in cell O11 finds the root 2 based on the initial guess of 1.

WebFeb 14, 2013 · I found out it's relatively easy to implement your own root finder using the scipy.optimize.fsolve.
