i added a photo of the situation
inside an ellipse (its formula x^2 /a^2 + y^2 /b^2 =1)
we block an isosceles trapeze .
the large base of the trapeze is on the X axes.
show that the maximal space of the trapeze is 3^0.5( a*b)?
i tried to get the feild of the trapeze by signing the height by X
but if i connect it to the ellipse formula for as xb
i need another variable for the small base of the trapeze.
how can i solve it?
i tried by integrals but i dont know the formula of the trapeze fonction
what to do?
how do i prove that the maximal space of the trapeze is 3^0.5( a*b)?
plz help
