1. The problem statement, all variables and given/known data

Hi, I am not asking for solution for any problem as i already have the given solution for the problem. Instead, what i want clarify is what do they mean by the odd and even function and how do they get 0? Also, is there a need to change the order from dxdy to dydx?

It's even.

If the all exponential numbers are even the function is even, if all are odd function is odd and if there are both odd and even exponential numbers the functions is neither odd nor even.

And the sum of any two even functions?

If you want to generalise, you should be thinking about general even and odd functions.

If so, try plugging in $x = 1$ and $x = -1$, say, and see how the function values compare.

I'm not the one who confused about the even-odd functions :D You should say it to topic owner
