@eroshea Try this f(x)=x^3+3(a-7)x^2+3(a^2-9)x-2 For what values of a does the function has a positive point of maximum
Construct a window in the shape of a semi-circle over a rectangle. If the distance around the outside of the window is 12 feet, what dimensions will result in the rectangle having largest possible area ? ----can you make a problem like that?? coz i don't have any idea on how.. this is just a project for my calculus and we haven't took that lesson.. and is related to Civil Engineering.
This will be the application part of maxima & minima .. Let me see if i can help u :)
owh i see.. it should be Application then.. :D i'll wait :))
Have u solved the question u had given here ??
1)Show that a rectangle of maximum area that can be inscribed in a circle is a square ? 2)Prove that perimeter of ractangleof given area is minimum if it is a Square
and i don't know how.. -_- im sorry.. i don't have an idea about that..
so its saying 12 feet perimeter?
if u want to make a question like that its simple, u just need to ask 2 things at once
say you have a pool and the perimeter around the pool must be 50 feet, and the area of the pool must be maximized.. what are the dimensions
@dan815 Thanks Dan . U saved my effort :)
thanks!! that will be very helpful! :))
wait... so how should i state the problem of that? and please give me the solutions too if possible.. i really dont know how to deal with that
Hi here is the solution for 2nd one .. See this & try out the first one :) . All the best
thanks so much! :))
but is that related to Civil Engineering????
These are general concepts of engineering , Applicable to any branch . Are u persuing civil engineering ??
yes.. coz that is what my project is all about.. it should be related to my course Civil Engineering..
can i have a better picture that you have posted?
what u wanna do
well, my professor gave my project back coz he said that the values should be variables.. and the picture that was posted here has that kind of solutions.. but it is cut on the right so i can't see the full solution.
