Okay so I was watching this lecture.
http://ocw.mit.edu/courses/mathemat...ll-2006/video-lectures/lecture-1-derivatives/
Skip to 41 minutes
He's solving the area for a triangle, and I think he got the answer wrong.
The equation he got was
1/2 times (2x0)(2y0)
Some how he got this equation to = 2
However when I do it, the answer I get is 2x0y0
Because I do this:
1/2 times (2x0)(2y0)
4x0y0/2
which then is the same as 2x0y0
Some how he got 2 though as his answer. Am I missing some piece of information or something? I have no clue how he got the x0 and y0 to cancel out.
