Imagine I had a brick of mass 1kg that was drifting in space. If 1 Newton of force was applied on the brick for 1 second, would that increase the velocity of the brick by one 1m/s?

pic related. I need to find the voltage inside the box using excel (numerical method of laplace equation). i was thinking of doing the thing on the right except i'd replace 300, 100, and 20 with 0V and i's use 100V instead of 140. Also, it would be 12 cells across and 10 cells down. is my train of though correct?

yes

How do I calculate residues?
I have a function
[math]f(z)=\frac{\pi\cot (\pi z)}{z(z+1)}[/math]
With poles at [math]z=0,\quad z=1[/math]
How do I find the residues in these points?
Carter Reed
Small error, z is -1, not 1 obviously.

Hello Veeky Forums,
brainlet here.
I am having an embarassing problem... why the hell is the derivative of y=62x-2x^2=50 if x is equal to 3 but 62*3-2*3^2-(62*2-2*2^2)=52?
I have literally no idea. Can someone give me an illuminating explanation? thank you.

>y=62x-2x^2=50
Is y=62x-2x^2 or y=50?
Xavier Stewart
it's 50 if x=3 is what I meant. Sorry for being unclear.
