Mmm, not exactly. I'm quite behind in my work, and I don't really see how to use the info you gave me there... I'm particularly confused by the symbol θ ? I honestly don't know what that symbol is supposed to mean for this equation.
the symbol looks unclear in the problem but is it suppose to look like a zero with a horizontal line in it? if so its just a variable. it is like having x in there.
