If t represents time and v represents stock value, I have the following questions:
What does the area under the curve represent?
What does the product $v_i*L_{i-1}$ represent?
What does $ \sum v_i*L_{i-1}$ ?
Could using vectors help if we assume that the line segments are vectors?
What I am looking for is a representation or a meaning similar to that given such as $velocity=dx/dt$ and that Area under a velocity-time graph = distance traveled. Even a formula to represent the sum will be an answer.
I tried to find a logical meaning for what the above represent but could not find any!
This is not a homework.
Your help is appreciated. Thx.
