I think it is a good solution. Nonetheless, it's too complicated for my case. Thank you so much.

Thanks for your response.

Express as polynomial form. This is in spreadsheet formula. I have alternative solution, using "if" command. However, I'm trying to find a solution in math.

Thanks for reply. Yes, it exactly is express form of function. It's not homework but created by myself when I solve a problem in my job.

My problem is simple, but I couldn't solve it: This is: Find a function f(x) of a variable x, x is in real field. the F(x) satisfy: When x = 0, f(x) = 0 When x<>0, f(x) =1. Anyone can help me? Thank you.

Thank you. Apologize for my mistake.

Are there anything new in String theory?
