Yes, that's what I want to know. What other information do you need ?

How can we calculate the speed of a vehicle from pedestrian throw distance ? If the weight of a vehicle is 1220 kg and a pedestrian's weight is 72 kg. Throw distance is 20.70 meters.

Thank you very much tiny-tim. I found now the paramters. a=5 and b=4.

I understand that in this point the derivative should be 0. So I found the derivative ,equaled to zero and I replaced (pi/3=x) . But I'm not sure, should I equal the function with 1/4 to find the ordiante ?

Find a, b parameters such that the function such that the function $f(x)= (sin2x)/(a-bcosx)$ has extreme value in point (pi/3,1/4)
