I am trying to find the three roots from x=0 to x=2∏ for this equation: x*Sin[x] + 1.5 x - 3. I want to divide the graph into intervals of say from x=1.0 to x=2.0 as one interval and so on and so forth. How do I go about inserting that code into my existing codes? I am using the bisection method to solve this equation. I thought of just replacing the intervals one by one but I don't think it's very feasible. Could anyone of you guide me on how to go about doing it? I'm using Mathematica 8. Thanks!
