AI Thread Summary
The expression given is simplified incorrectly by the user, who arrives at a different result for C. The textbook simplifies the expression to C = -2, while the user’s calculations lead to a more complex form. A key error is identified in the user's initial step, where they should have multiplied by 9 instead of 3 to eliminate the denominators properly. The correct approach leads to the conclusion that C = -2 is indeed accurate. Proper simplification methods are crucial for obtaining the correct result in such expressions.

My textbook has the expression

$$\frac{4}{9} + 2 - 44 = C(\frac{11}{3})(\frac{17}{3})$$

and it simplifies it to $C = -2$

But I am getting

$$(\frac{4}{9} + 2 - 44) * 3 = C187$$

which simplifies to

$$(\frac{12}{9} + 6 - 132) = C187$$

and

$$(\frac{12}{9} - 126) = C187$$

then,

$$(\frac{4}{3} - \frac {378} { 3}) = C187$$$$( - \frac {374} { 3}) = C187$$

then

$$( - \frac {374} { 561}) = C$$

Am I wrong?

In your first step, where you multiplied through by 3...you need to multiply through by 9 in order to clear both of those denominators on the right side. :)

Hints (more like suggestions):
Start with obvious:
4/9 - 42 = 187C / 9 ; multiply by 9:
4 - 378 = 187C
 
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...
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...
