AI Thread Summary
A heading of 330 degrees is indeed equivalent to a standard angle measurement of 30 degrees when considering the direction relative to north. The calculation involves subtracting the heading from 360 degrees, resulting in 30 degrees west of north. The discussion highlights the confusion surrounding the terminology of "standard angle" versus heading measurements. Clarification on how headings are measured is provided, emphasizing that 0 or 360 degrees indicates true north. Understanding these concepts is essential for accurate navigation and angle interpretation.

Hi all,

Would a heading of 330 degrees be equivalent to a standard angle measurement of 30 degrees? I'm used to calculating by subtracting the heading from 90, but the angle is too large for this problem. I know it seems to be a ridiculously simple question compared to others on this forum, but it's fairly difficult to find information about headings vs. standard on the internet.

Thanks! :smile:

I'm unfamiliar with your use of 'standard angle' measurement. But as for how a heading is measured, this should answer that detail: http://en.m.wikipedia.org/wiki/Course_(navigation )

Does that help?

A "heading" of 0 or 360 degrees is due north. 330 degrees is 360- 330= 30 degrees "west of north".
 
Ah, okay. That is what I thought. Thank you!
 
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...
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'
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...
