FSOLVE

Syntax

FSOLVE (equation, symbol, number, number )

Implemented in iMath since version 2.3.6.

Explanation

Numerically solve the equation for the symbol. It is assumed that the soluation lies between the lower and upper bounds given as arguments. A Newton-Raphson algorithm is used.

Example

EQDEF 192 x^{6} - 512 sqrt{3} x^{5} + 1104 x^{4} - 384 sqrt{3} x^{3} + 132 x^{2} - 1 = 0

EQDEF FSOLVE(@prev@, x, -0.2, -0.05)

This will find the solution x = -0.073145130133813430764
