welcome to pf!

hi maan143! welcome to pf! :wink:

Show us what you've tried, and where you're stuck, and then we'll know how to help! :smile:
 
Is the point A supposed to be the vertex? If not, the problem is unworkable and if so the picture should show a slope of 0 at A.
 
Thanx. for ur replies.

mmm... actually I wanted to make it as simple as possible, so I drew this figure for easy understanding of the prob.

okay! here's the link, www.youtube.com/watch?v=zVKf6hZfrhA&feature=related

just seek upto 25:24
why did he take 1/3 * 0.45fck * 0.57x
Why not 1/6 * 0.45fck * 0.57x

where, 0.45fck = 5 (in previous thread figure)
0.57x = 6 (in previous thread figure)
0.43x = 4 (in previous thread figure)and don't worry (consider) 'b' in the youtube video, coz we are considering only area (2-D)Now did I make the prob. clear to you guys and let me know, if I didn't .

Thanx. again.
 

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 'Fermat's Last Theorem'

Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...

Thread 'Useless continued fraction for 1'

I'm interested to know whether the equation $$1 = 2 - \frac{1}{2 - \frac{1}{2 - \cdots}}$$ is true or not. It can be shown easily that if the continued fraction converges, it cannot converge to anything else than 1. It seems that if the continued fraction converges, the convergence is very slow. The apparent slowness of the convergence makes it difficult to estimate the presence of true convergence numerically. At the moment I don't know whether this converges or not.
