Hello :-),

How can I differentiate the follwing function:

Cq = Cao*k1*t / [(1+k1*t)*(1+k2*t)]

If want to find the maximum:

dCq/dt = 0

I can solve if of course by hand. The solution is t=1/sqrt(k1*k2)

I tried it with maple, but I got a strange result (see picture). How can I use maple to get the right result?

Thank you very much!

How can I get maple to express the end result more compact/dense. Like for example in the picture, why can the program not just sum up all the fractions and everything in one number?
