That is what I thought. But I'm still lost as far as what to do here...
The gradient is just the partial derivatives with respect to x and y. If those were equal to zero then there would be no change in elevation, or am I understanding this completely wrong? :cry:
If you're given a point, with coordinates (0.8,0.7,0.129), and its elevation is given by f(x,y)=(e^(-0.5(x^2+y^2))*sin(pi*x+2pi*cos(5y)). How would you determine which direction to move in, where the elevation would not change?
How would I find the volume of a pyramid with an equilateral triangle as it's base? I know how to do a pyramid with a square base (the integral from 0 to it's height of 2*(equation solved for y of a side)^2 dy)). Would this be the same method?
So that means that what was normally constructive, (ΔL/λ=0,1,2...) will now be completely destructive since the transmitters are out of phase? So I could still use ΔL/λ=0,1,2... at the bisection?
Need some help getting started...
Two radio transmitters are placed 50 m apart on either side of a runway. The two transmitters will broadcast the same frequency, but out of phase with each other. This will cause a nodal line to extend straight off the end of the runway. As long as the...
1. Why does the dissolution of NH4NO3 happen if the ∆H is 28.1? I'm supposed to be detailed with an equation, and explaining spontaneity.
Does it happen because of the energy created from protonation?
2. And why is only a strong base able to make H3PO4 act as an acid after the 3rd acid...
