The answer(s) of interest is(are) the yval values, the xval values are the bounds of the search interval. If those are the bounds you are interested in, you may try :

roots=[]
for xval in [-10..5, step=.1]:
try;
yval = find_root(cos(x)-exp(x), xval, xval+.1
root.append((xva, yval, xval+.1))
except:
pass


which gives you a list of solution bracketed by the search bounds leading to them, but I have trouble seeing the point...
