Can someone help me with a double integral? Its been a long time and I forgot

Question

chrisplusian · Answer

$$\int\limits_{0}^{\pi/2}dy \int\limits_{0}^{5}xdx$$

anonymous · Answer

What's the problem?

chrisplusian · Answer

$$\int\limits_{0}^{\pi/2}(dy)  \int\limits_{0}^{5}(xdx)$$

chrisplusian · Answer

did it show up that time?

anonymous · Answer

Yes, it's there, but where exactly do you need help?

anonymous · Answer

Just integrate respect to dx and dy separately, remember integrating a constant will give you a variable, and integrating just a variable is 
(x^(n+1))/(n+1)

anonymous · Answer

$$\large y |_{0 \rightarrow \pi/2} \times \frac{ x^2 }{ 2 } |_{0 \rightarrow 5}$$
