Hi everyone! I'm an economics student and this year I'm studying quantitative techniques. Sometimes, while going the math problems I find some difficult questions which I can't solve. The thing is I've no teacher to guide me, to help me. I read with the help of my books only. So I searched in net to find a good forum where I can post my doubts and I registered in this cool site. I hope you people will help me out. By the way can I post here those problems which are related to “ application of mathematics in economics"?
