Hello

I have plotted a changing distance (d(x)) with time using cftool and calculated the function. Its derivative was calculated and this is v(x). when plotted with fplot the initial Y values are 0. I am calculating the x position at which this rises above the x axes (y>0). To do this i made v(x) equivalent to 1 (==1) and evluated x yet:

>>v(x)==1

ans =

(4119*x^2)/10000 - (1787*x)/5000 + 891/2500 ==1

>> eval x

x =

x

Will someone please help to calculate this? i can measure the x value directly. It is preferable to standardise this procedure.

GS.
