A little graph help please?

  1. Nov 7, 2005 #1
    Okay, so my question is: given the picture below, how can I find the area below the graph (in the shaded region) ? It's for a lab that I did in class, but it wasn't until i finished the whole picture that i realized that I didn't know how to calculate the area of this graph.

    If an estimate is good enough, just notice that each square represents 0.16*1 Nm = 0.16 Joules. Then just add up the squares and estimate for the non-complete squares.
