# Help with double integral and switching the order of the differentials

1 1/2
∫ ∫ e-x2 dx dy
0 y/2

## Homework Equations

***Graph equation***

## The Attempt at a Solution

I graphed the function and they made a horizontal strip. However, I can't seem to find the right function with a vertical strip, which is where I'm stuck.

$$\int_{y=0}^{y=1}\int_{x= y/2}^{x= 1/2} e^{-x^2}dx dy$$
