AI Thread Summary
The discussion centers on calculating the height of a statue using the angle of elevation and various trigonometric relationships. The formula presented involves variables such as alpha, beta, and 'a,' but lacks clarity on their definitions and relationships. Participants request a diagram to better understand the variables and their roles in the calculation. There is confusion regarding the angle of elevation 'x' and its absence in the provided formula. Clarifying these points is essential for demonstrating the relationship accurately.

(90) on a column stands a statue of length b. From some point
If the foot of the statue with an angle of elevation x. approaching the observation point a distance to the column, the part looks more high from the same angle increased in betha statue. Demonstrate that (see figure)

from figure I see sinalpha/cos(alpha) (a -acosbetha+bsinbetha) = a sen (betha) -b+bcos(betha)
I think this is that I must demonstrateView attachment 2088

You mention an angle of elevation $x$, but it is not present in the formula attached. What does $a$ represent?

Please attach a diagram so that we can see what the variables actually represent.

Sorry
x is alpha in the formula or image
 

Thread 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...

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...
