Dear expert:I want to maximize function called f(t)

f(t) = a1t+a2(1-t)/(b1t+b2t+b3t+c1(1-t)+c2(1-t)+c3(1-t))

s.t 0=<t<=1

(a1、a2、a3、b1、b2、b3、c1、c2、c3 just some values)

However, since the function I want to maximize is the division of two affline functions,so the error occurs.

I think there should be some special skills to deal with this problem, I would like to ask the experts to give me some advice,thank you!
