Well for starters, we know the exponential function is always positive.

We know that for all , so that means the product of two sine functions is also going to be bounded between these two values.

Therefore the range of is . - Feb 25th 2013, 10:23 PMfashionsportRe: Multivariable Calculus Problem
Thanks so much! That's exactly what I was looking for

Btw do you mind clarifying your first sentence? As in, why should you write just (-∞, 0)∪(0, 9) and not x∈(-∞, 0)∪(0, 9)? Thanks again

EDIT: Or I guess what I mean is, how do you define your variable with interval notation? It seems no one ever says "x" anywhere when they say their answer in interval notatio
