3. The area of a rectangle is 4cm^2.
Find the dimensions of the rectangle so that the distance from one vertex
to the midpoint of a non adjacent side is minimum.

kirishi said:thanks soo much....
for question #1 what would the equation be??
so far i did this much:
v=area of a cross section x length
=area of trapezoid x length
=1/2 (5)(4) x (10)
=100
now what do i do??
Differentiate, then set to zero.kirishi said:for #3 do i make z equal to zero then solve to find wat the points r?? so it would b:
(x^4+64)^1/2=0
x^4+64=0
x^4=-64
now wat do i do??
Yes, many kiddies use cutesy kiddie-speak -- with other kiddies. But if you're going to come to a grown-up environment and ask grown-ups to help you, it might be wise (and certainly would be polite) to speak clearly.kirishi said:listen if you don't want to take me seriously then don't ok...and i am not the only one who writes like this...i just asked for help....
u need the derivative.5. Find the area of the triangle formed by the three points on the curve \(\displaystyle \L y\:=\:\left(\frac{x^2\,-\,1}{x^2\,+\,1\right)^2\)
where the slopes of the tangent lines to the curve at those points are zero.
