AI Thread Summary
The equation Y = -0.00331x + 9907.333 describes a linear relationship between distance (x) and elevation (y), with a gradient of -0.003311. To convert this gradient into parts per thousand, it indicates that for every 1,000 units moved in the x plane, the elevation changes by -3.311 units in the y plane. The discussion clarifies that parts per thousand refers to movement in the y plane relative to movement in the x plane. Therefore, for every 1,000 units in the x direction, the corresponding change in the y direction is -3.311. Understanding this conversion is crucial for interpreting gradients in practical applications.

Hello all

I was wondering if anyone could help me with the following:-

The equation of a line is Y = -0.00331x + 9907.333.

The equation represents distance (x) and elevation (y)

The gradient is -0.003311. What is number represents is for every 1 unit I move in the x plane I move -0.003311 in the y plane.

My question is how do I convert -0.003311 into parts per thousand?

Does part per thousand mean for every 1000 units I move in the x plane how much do I move in the y plane or does it mean for every 1000 units I move in the y plane, how much do I move in the x plane??

Can anyone help?

Thank you in advance

It's the former.

Thread 'Video on imaginary numbers and some queries'

Hi, I was watching the following video. I found some points confusing. Could you please help me to understand the gaps? Thanks, in advance! Question 1: Around 4:22, the video says the following. So for those mathematicians, negative numbers didn't exist. You could subtract, that is find the difference between two positive quantities, but you couldn't have a negative answer or negative coefficients. Mathematicians were so averse to negative numbers that there was no single quadratic...

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...

Thread 'Unit Circle Double Angle Derivations'

Thread 'Unit Circle Double Angle Derivations'

Here I made a terrible mistake of assuming this to be an equilateral triangle and set 2sinx=1 => x=pi/6. Although this did derive the double angle formulas it also led into a terrible mess trying to find all the combinations of sides. I must have been tired and just assumed 6x=180 and 2sinx=1. By that time, I was so mindset that I nearly scolded a person for even saying 90-x. I wonder if this is a case of biased observation that seeks to dis credit me like Jesus of Nazareth since in reality...
