Hi Everone,

I have a problem that I am struggling to solve, I am very new to intergration and until now I have been coping OK. I am strugling to identify the significance of the 2 before the intergral sign, Please can someone advise how I tackle this problem.. Thanks,

2 \int 470 di

I am sorry but I dont know how to right the limits on here but the upper limit is 1.0 and the lower is 1.00
