Hello,

 

I need to solve numerically a nonlinear equation. I am looking the first value t1 ≥ t0 because I am iterating this process '' n '' times.  I have to compute t1 ≥ t0 for S1  ------>  change S1 by S2 and compute t2≥ t1, etc...

Examples:   S:= 1 + 2.sin(t) - 1.9.t ; 

Result:= Student-Calculus1:-Roots( S = 0, numeric, t = t0..infinity ) ----> Does not work,  why ?

Result:= Student-Calculus1:-Roots( S = 0, numeric, t ≥ t0 )  ---------------> Does not work,  why ? 

Result:= Student-Calculus1:-Roots( S = 0, numeric, t  = t0... t0+ constante )  ---------------> works,

but t1 can be outside of this interval. This implies that Result can be [ ] .  This does not make sens.

Thanks for helping
