Thursday, 5/12 -- Algebra I Milestones

Analytic Geometry Test is tomorrow!

For the past two weeks, we have studied similarity and congruence pertaining to triangles.  Posted here is the review that we worked on today in class.

Oh, yeah: I sent a tweet out earlier about someone's birthday.  He was almost a Leap Year baby.

Calculus Class Today

OK, I found my mistake and it makes for beautiful stuff.

First, here is where we were...

When I cancelled out the square from n, I forgot to carry the n through.  It is below in red.

So, instead of taking out the 1/3, I just broke up the numerator and made three fractions with 3n as the denominator.

Then, I distributed the 2/n back through and simplified.

Since this is a limit at zero, everyone with an n in the denominator goes to zero.

That leaves us with adding the constants.

When we bring back in what we determined about the integral of 2 from earlier, we get...

If you remember, our estimate with the rectangles and trapezoids was 12.75.  Look how close we got to the actual area, using just 4 rectangles or 4 trapezoids.  I wonder how many more rectangles or triangles would shrink that 0.08333... difference?
