AI Thread Summary
The discussion focuses on understanding the conversion of equation A into equation B, specifically the equation Mrc= 2/3Pcb x b x 1/2d1 x 3/4d1. A user requested a step-by-step explanation of the process, which involves simplifying the multiplication of fractions and recognizing the properties of exponents. Key points include that multiplication does not require distribution and that the products of the fractions lead to a simplified form of 1/4Pcb x b x (d1)^2. The explanation provided clarified the confusion, allowing the user to understand the conversion process better. Overall, the discussion highlights the importance of clear mathematical communication and the use of proper notation.

I am reading this in a book and am having trouble understanding this.

Can someone explain the step by step the process in changing equation A into equation B?


Mrc= 2/3Pcb x b x 1/2d1 x 3/4d1

= 1/4Pcb x b x (d1)2



Many Thanks

It is almost impossible to understand what you wrote (for me it is completely impossible). Please do learn how to use LaTeX within this site to write mathematics.

It made perfect sense,

Remember that multiplication, does not require any distribution, that is, some students write

A(BC)=(AB)(AC). This is wrong. They are thinking of A(B+C)=AB+AC.

So multiplication only needs to happen once.

you have a copy of 2/3, 1/2 and 3/4. Take the first two 2/3 and 1/2, their product is 1/3.

Then 1/3 times 3/4 is 1/4. They also have two copies of d1, so that is (d1)^2.

I'm assumig by d1, you meant d_1
 
Thanks Algebrat,

You have explained it very clearly, and now I understand.
 

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...
