AI Thread Summary
The discussion centers on the challenges faced in solving complex rational equations due to a lack of proper guidance and resources. The original poster expresses difficulty with rational equations after their teacher has been absent, leading to inadequate instruction. They seek help with specific problems, highlighting the need for foundational understanding in manipulating denominators. A suggestion is made to eliminate denominators by multiplying through by the highest powered denominator to simplify the equations. It is emphasized that solutions must be checked against the original equations to avoid invalid results.

Ok, so before every says that I am just looking for answers, I would like to say my teacher has been on "stress leave" for the past 5 weeks and we have been tought by a very bad "math" teacher

Im having a hard time with Rational Equations, I guess because I have no notes on it :cry: So I am looking for some help. I was given a sheet and have to have it done but since I can only do a few, I am asking for your help...

Question #1
7/s-1 - 10/s^2-s = s+2/s I don't even know where to start

Question #2
2y/y^2+3y-10 + 4/y^2+6y+5 = 3y/y^2-y-2

Start off by getting rid of the annoying denominators. Multiply through the equations by the highest powered denominator you can find and it'll turn into a much friendlier equation.

Just remember that none of the denominators can equal zero, so you must check your solutions with the original equation!

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 '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...
