Calculatrice de zéros

Trouver les zéros d'une fonction pas à pas

La calculatrice essaiera de trouver les zéros (exacts et numériques, réels et complexes) de la fonction linéaire, quadratique, cubique, quartique, polynomiale, rationnelle, irrationnelle, exponentielle, logarithmique, trigonométrique, hyperbolique et de la valeur absolue sur l'intervalle donné.

Enter an equation:
Like x^2+3x+4=0 or sin(x)=x.
Find the solution with respect to:
Enter an interval: ,
Leave empty, if you don't have any restrictions.
Only real roots will be searched for if you specify the interval, regardless of whether the box is checked.

If the calculator did not compute something or you have identified an error, or you have a suggestion/feedback, please contact us.

Your input: solve the equation x416x3+90x2224x+245=0 for x on the interval (,)

Answer

Real roots

x=5

x=7

Complex roots

x=2+3i2.0+1.73205080756888i

x=23i2.01.73205080756888i
