my code doesnt act like i want him to...
thats the code:
y = 1.1*x.^3+400*x.^2-5.5*10^5*x-9.7*10.^6+exp(-(x+1111));
Nullstellen = vpasolve(y);
yx = diff(y);
XPx = vpasolve(yx)
ive tried it also with solve.. i dont know how to get complex solutions and XPx only gets one solutions but it has to be three..
Thanks in advance!
