@IrishBoy123 please help

Answer 6

"method of quadrature"

i looked that up earlier and Wiki describes it as an old/ancient term for what we now call Rieman (sp?) sums.

so i guess this is pre-calc numerical solutions for the area under a curve.

@melstutes? is that what you are trying to learn?!

Answer 7

This is a math essentials class. It is a virtual class that is supposed to be an introductory class. I have never had geometry so I am lost with this.

Answer 10

Thank you mathmath

Answer 11

Can anyone help solve a different way?

Answer 12

This is the definition from the class quadrature - The area of an enclosed region on a plane that can be approximated by the sum of the areas of a number of rectangles.

Answer 13

there may be way by calculus @Michele_Laino might know, idk much calculus

Answer 14

I am stumped and don't know where to begin.

Answer 16

I can try to solve using the rectangles approximation method, nevertheless I'm not sure that it is the requested method

Answer 17

ok! we have to divide the interval into for example three subintervals, as below:
\[\begin{gathered}
{x_0} = 0, \hfill \\
{x_1} = 1 \hfill \\
{x_2} = 2 \hfill \\
{x_3} = 3 \hfill \\
\end{gathered} \]
